PyYAML 5.1 through 5.1.2 has insufficient restrictions on the load and load_all functions because of a class deserialization issue, e.g., Popen is a class in the subprocess module. See CVE-2019-20477. NOTE: this issue exists because of an incomplete fix for CVE-2017-18342.

Pyyaml version 5.4 includes a fix for CVE-2020-14343: A vulnerability was discovered in the PyYAML library in versions before 5.4, where it is susceptible to arbitrary code execution when it processes untrusted YAML files through the full_load method or with the FullLoader loader. Applications that use the library to process untrusted input may be vulnerable to this flaw. This flaw allows an attacker to execute arbitrary code on the system by abusing the python/object/new constructor. This flaw is due to an incomplete fix for CVE-2020-1747.

Tensorflow versions 2.5.3, 2.6.3, 2.7.1 and 2.8.0 include a fix for CVE-2022-23563: In multiple places, TensorFlow uses 'tempfile.mktemp' to create temporary files. While this is acceptable in testing, in utilities and libraries it is dangerous as a different process can create the file between the check for the filename in 'mktemp' and the actual creation of the file by a subsequent operation (a TOC/TOU type of weakness). In several instances, TensorFlow was supposed to actually create a temporary directory instead of a file. This logic bug is hidden away by the 'mktemp' function usage. It was replaced 'mktemp' with the safer 'mkstemp'/'mkdtemp' functions, according to the usage pattern.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2 and 2.2.1 update its dependency "SQLite" to handle CVE-2020-11655.

Tensorflow is an Open Source Machine Learning Framework. When decoding a tensor from protobuf, a TensorFlow process can encounter cases where a `CHECK` assertion is invalidated based on user controlled arguments, if the tensors have an invalid `dtype` and 0 elements or an invalid shape. This allows attackers to cause denial of services in TensorFlow processes. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Impact: A recurring instance of CVE-2022-35935 has been observed and addressed. In this case, `SobolSample` is prone to denial of service due to assumed scalar inputs. You can replicate this using the following code in Python:

```python 
import tensorflow as tf 
tf.raw_ops.SobolSample(dim=tf.constant([1,0]), num_results=tf.constant([1]), skip=tf.constant([1])) 
```

Patches: Corrective measures have been taken and the issue has been patched via GitHub commits c65c67f88ad770662e8f191269a907bf2b94b1bf and 02400ea266bd811fc016a848445de1bbff3a23a0. These fixes will be integrated in the forthcoming TensorFlow 2.11 release and will also be added to TensorFlow 2.10.1, 2.9.3, and 2.8.4 as they fall within the supported range. Furthermore, the initial commit will be incorporated into TensorFlow 2.7.4.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, and 2.3.1 include a fix for CVE-2020-15208: In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, when determining the common dimension size of two tensors, TFLite uses a "DCHECK" which is no-op outside of debug compilation modes. Since the function always returns the dimension of the first tensor, malicious attackers can craft cases where this is larger than that of the second tensor. In turn, this would result in reads/writes outside of bounds since the interpreter will wrongly assume that there is enough data in both tensors. The issue was patched in commit 8ee24e7949a203d234489f9da2c5bf45a7d5157d

Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41223: In affected versions, the implementation of 'FusedBatchNorm' kernels is vulnerable to a heap OOB access. The fix is included in TensorFlow 2.7.0.

Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41217: In affected versions, the process of building the control flow graph for a TensorFlow model is vulnerable to a null pointer exception when nodes that should be paired are not. This occurs because the code assumes that the first node in the pairing (e.g., an 'Enter' node) always exists when encountering the second node (e.g., an 'Exit' node). When this is not the case, 'parent' is 'nullptr' so dereferencing it causes a crash. The fix is included in TensorFlow 2.7.0.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, and 2.3.1 include a fix for CVE-2020-15209: In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, a crafted TFLite model can force a node to have as input a tensor backed by a "nullptr" buffer. This can be achieved by changing a buffer index in the flatbuffer serialization to convert a read-only tensor to a read-write one. The runtime assumes that these buffers are written to before a possible read, hence they are initialized with "nullptr". However, by changing the buffer index for a tensor and implicitly converting that tensor to be a read-write one, as there is nothing in the model that writes to it, we get a null pointer dereference. The issue was patched in commit 0b5662bc.

This can be used by attackers to run arbitrary code on the plaform where the CLI tool runs. However, given that the tool is always run manually, the impact of this is not severe. The issue has been patched by adding a 'safe' flag which defaults to 'True' and an explicit warning for users.

Selected versions of TensorFlow are subject to a Denial of Service (DoS) vulnerability due to an issue in the implementation of depthwise operations. This vulnerability arises when a tensor's element count overflows as a result of an assertion failure, triggered by specific inputs and filter sizes in depthwise convolution backpropagation operations. The vulnerability is linked to an incomplete remediation of CVE-2021-41197.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2 and 2.2.1 updates its dependency "SQLite" to handle CVE-2020-13871.

Tensorflow versions 2.5.3, 2.6.3 and 2.7.1 include a fix for CVE-2021-41206: In affected versions, several TensorFlow operations are missing validation for the shapes of the tensor arguments involved in the call. Depending on the API, this can result in undefined behavior and segfault or 'CHECK'-fail related crashes but in some scenarios writes and reads from heap populated arrays are also possible. These issues were discovered internally via tooling while working on improving/testing GPU op determinism. As such, there aren't reproducers and there will be multiple fixes for these issues.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1 include a fix for CVE-2020-15203: In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, by controlling the 'fill' argument of tf.strings.as_string, a malicious attacker is able to trigger a format string vulnerability due to the way the internal format use in a 'printf' call is constructed. This may result in segmentation fault.

Tensorflow versions 2.6.4, 2.7.2, 2.8.1 and 2.9.0 update 'curl' to v7.83.1 to handle CVE-2022-27778.

Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41198: In affected versions, if 'tf.tile' is called with a large input argument, then the TensorFlow process will crash due to a 'CHECK'-failure caused by an overflow. The number of elements in the output tensor is too much for the 'int64_t' type and the overflow is detected via a 'CHECK' statement. This aborts the process. The fix is included in TensorFlow 2.7.0.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1 include a fix for CVE-2020-15195: In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the implementation of 'SparseFillEmptyRowsGrad' uses a double indexing pattern. It is possible for 'reverse_index_map(i)' to be an index outside of bounds of 'grad_values', thus resulting in a heap buffer overflow.

TensorFlow updates its curl dependency from version 8.2.1 to 8.4.0 to address CVE-2023-38546.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1 include a fix for CVE-2020-15202: In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the 'Shard' API in TensorFlow expects the last argument to be a function taking two 'int64' (i.e., 'long long') arguments. However, there are several places in TensorFlow where a lambda taking 'int' or 'int32' arguments is being used. In these cases, if the amount of work to be parallelized is large enough, integer truncation occurs. Depending on how the two arguments of the lambda are used, this can result in segfaults, read/write outside of heap allocated arrays, stack overflows, or data corruption.

https://github.com/tensorflow/tensorflow/security/advisories/GHSA-rmg2-f698-wq35

Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41201: In affected versions, during execution, 'EinsumHelper::ParseEquation()' is supposed to set the flags in 'input_has_ellipsis' vector and '*output_has_ellipsis' boolean to indicate whether there is ellipsis in the corresponding inputs and output. However, the code only changes these flags to 'true' and never assigns 'false'. This results in unitialized variable access if callers assume that 'EinsumHelper::ParseEquation()' always sets these flags. The fix is included in TensorFlow 2.7.0.

The effect of CVE-2022-35991 was seen once more, where TensorListScatter and TensorListScatterV2 could potentially crash due to non scalar inputs in the element_shape parameter while in eager mode. This issue has been identified and resolved. The issue was identified when the following Python code was executed:

```python 
import tensorflow as tf 
arg_0=tf.random.uniform(shape=(2, 2, 2), dtype=tf.float16, maxval=None) 
arg_1=tf.random.uniform(shape=(2, 2, 2), dtype=tf.int32, maxval=65536) 
arg_2=tf.random.uniform(shape=(2, 2, 2), dtype=tf.int32, maxval=65536) 
arg_3='' 
tf.raw_ops.TensorListScatter(tensor=arg_0, indices=arg_1,  element_shape=arg_2, name=arg_3) 
```

A patch to resolve this issue is available in the GitHub commit bf9932fc907aff0e9e8cccf769e8b00d30fd81a1. This fix will be part of TensorFlow 2.11. Additionally, the commitment will be selected for TensorFlow 2.10.1, 2.9.3, and TensorFlow 2.8.4, as these versions are also known to be affected and still under supported range.

Tensorflow is an Open Source Machine Learning Framework. When decoding PNG images TensorFlow can produce a memory leak if the image is invalid. After calling `png::CommonInitDecode(..., &decode)`, the `decode` value contains allocated buffers which can only be freed by calling `png::CommonFreeDecode(&decode)`. However, several error case in the function implementation invoke the `OP_REQUIRES` macro which immediately terminates the execution of the function, without allowing for the memory free to occur. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Tensorflow is an Open Source Machine Learning Framework. There is a typo in TensorFlow's `SpecializeType` which results in heap OOB read/write. Due to a typo, `arg` is initialized to the `i`th mutable argument in a loop where the loop index is `j`. Hence it is possible to assign to `arg` from outside the vector of arguments. Since this is a mutable proto value, it allows both read and write to outside of bounds data. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, and TensorFlow 2.6.3, as these are also affected and still in supported range.

Tensorflow versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2 and 2.4.0 includes a fix for CVE-2020-26268: In affected versions, the tf.raw_ops.ImmutableConst operation returns a constant tensor created from a memory mapped file which is assumed immutable. However, if the type of the tensor is not an integral type, the operation crashes the Python interpreter as it tries to write to the memory area. If the file is too small, TensorFlow properly returns an error as the memory area has fewer bytes than what is needed for the tensor it creates. However, as soon as there are enough bytes, the above snippet causes a segmentation fault. This is because the allocator used to return the buffer data is not marked as returning an opaque handle since the needed virtual method is not overridden.

Tensorflow 2.11.1 and 2.12.0 include a fix for CVE-2023-25674: Versions prior to 2.12.0 and 2.11.1 have a null pointer error in RandomShuffle with XLA enabled.

Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41195: In affected versions, the implementation of 'tf.math.segment_*' operations results in a 'CHECK'-fail related abort (and denial of service) if a segment id in 'segment_ids' is large. This is similar to CVE-2021-29584 (and similar to other reported vulnerabilities in TensorFlow localized to specific APIs): the implementation (both on CPU and GPU) computes the output shape using 'AddDim'. However, if the number of elements in the tensor overflows an 'int64_t' value, 'AddDim' results in a 'CHECK' failure which provokes a 'std::abort'. Instead, code should use 'AddDimWithStatus'. The fix is included in TensorFlow 2.7.0.

Tensorflow versions 2.5.3, 2.6.3, 2.7.1 and 2.8.0 include a fix for CVE-2022-21727: The implementation of shape inference for 'Dequantize' is vulnerable to an integer overflow weakness. The 'axis' argument can be '-1' (the default value for the optional argument) or any other positive value at most the number of dimensions of the input. Unfortunately, the upper bound is not checked, and, since the code computes 'axis + 1', an attacker can trigger an integer overflow.

Tensorflow is an Open Source Machine Learning Framework. A malicious user can cause a denial of service by altering a `SavedModel` such that assertions in `function.cc` would be falsified and crash the Python interpreter. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Tensorflow versions 1.15.2 and 2.0.1 includes a fix for CVE-2020-5215: In TensorFlow before 1.15.2 and 2.0.1, converting a string (from Python) to a tf.float16 value results in a segmentation fault in eager mode as the format checks for this use case are only in the graph mode. This issue can lead to denial of service in inference/training where a malicious attacker can send a data point which contains a string instead of a tf.float16 value. Similar effects can be obtained by manipulating saved models and checkpoints whereby replacing a scalar tf.float16 value with a scalar string will trigger this issue due to automatic conversions. This can be easily reproduced by tf.constant("hello", tf.float16), if eager execution is enabled.

TensorFlow 2.4.0 includes a fix for CVE-2020-15265: In Tensorflow before version 2.4.0, an attacker can pass an invalid `axis` value to `tf.quantization.quantize_and_dequantize`. This results in accessing a dimension outside the rank of the input tensor in the C++ kernel implementation. However, dim_size only does a DCHECK to validate the argument and then uses it to access the corresponding element of an array. Since in normal builds, `DCHECK`-like macros are no-ops, this results in segfault and access out of bounds of the array. The issue is patched in eccb7ec454e6617738554a255d77f08e60ee0808 and TensorFlow 2.4.0 will be released containing the patch. TensorFlow nightly packages after this commit will also have the issue resolved.

Tensorflow versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2 and 2.4.0 includes a fix for CVE-2020-26267: In affected versions, the tf.raw_ops.DataFormatVecPermute API does not validate the src_format and dst_format attributes. The code assumes that these two arguments define a permutation of NHWC. This can result in uninitialized memory accesses, read outside of bounds and even crashes.

TensorFlow versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2, and 2.4.0 includes a fix for CVE-2020-26266: In affected versions and under certain cases a saved model can trigger use of uninitialized values during code execution. This is caused by having tensor buffers filled with the default value of the type but forgetting to default initialize the quantized floating point types in Eigen.

Tensorflow versions 2.5.3, 2.6.3, 2.7.1 and 2.8.0 include a fix for CVE-2022-21731: The implementation of shape inference for 'ConcatV2' can be used to trigger a denial of service attack via a segfault caused by a type confusion. The 'axis' argument is translated into 'concat_dim' in the 'ConcatShapeHelper' helper function. Then, a value for 'min_rank' is computed based on 'concat_dim'. This is then used to validate that the 'values' tensor has at least the required rank. However, 'WithRankAtLeast' receives the lower bound as a 64-bits value and then compares it against the maximum 32-bits integer value that could be represented. Due to the fact that 'min_rank' is a 32-bits value and the value of 'axis', the 'rank' argument is a negative value, so the error check is bypassed.

Tensorflow is an Open Source Machine Learning Framework. Under certain scenarios, Grappler component of TensorFlow can trigger a null pointer dereference. There are 2 places where this can occur, for the same malicious alteration of a `SavedModel` file (fixing the first one would trigger the same dereference in the second place). First, during constant folding, the `GraphDef` might not have the required nodes for the binary operation. If a node is missing, the correposning `mul_*child` would be null, and the dereference in the subsequent line would be incorrect. We have a similar issue during `IsIdentityConsumingSwitch`. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Tensorflow 2.8.4, 2.9.3 and 2.10.1 include a fix for CVE-2022-41894: The reference kernel of the 'CONV_3D_TRANSPOSE' TensorFlow Lite operator wrongly increments the data_ptr when adding the bias to the result. Instead of 'data_ptr += num_channels;' it should be 'data_ptr += output_num_channels;' as if the number of input channels is different than the number of output channels, the wrong result will be returned and a buffer overflow will occur if num_channels > output_num_channels. An attacker can craft a model with a specific number of input channels. It is then possible to write specific values through the bias of the layer outside the bounds of the buffer. This attack only works if the reference kernel resolver is used in the interpreter.

The Grappler component of TensorFlow has a susceptibility to a denial-of-service through a CHECK-failure during constant folding. This issue arises from the output_prop tensor, which has a user-controlled shape and can trigger one of the PartialTensorShape constructor's CHECKs. This flaw has been designated as TFSA-2021-198.

The problem has been addressed and rectified in the GitHub commit be7b286d40bc68cb0b56f702186cc4837d508058, which will be incorporated in TensorFlow 2.8.0.

However, the only check that the converted index is now valid is only present in debug builds. If the 'DCHECK' does not trigger, then code execution moves ahead with a negative index. This, in turn, results in accessing data out of bounds which results in segfaults and/or data corruption.

Tensorflow is an Open Source Machine Learning Framework. Under certain scenarios, TensorFlow can fail to specialize a type during shape inference. This case is covered by the 'DCHECK' function however, 'DCHECK' is a no-op in production builds and an assertion failure in debug builds. In the first case execution proceeds to the 'ValueOrDie' line. This results in an assertion failure as 'ret' contains an error 'Status', not a value. In the second case we also get a crash due to the assertion failure. The fix will be included in TensorFlow 2.8.0.

This occurs whenever the dimensions of 'a' or 'b' are 0 or less. In the case on one of these is 0, an empty output tensor should be allocated (to conserve the invariant that output tensors are always allocated when the operation is successful) but nothing should be written to it (that is, it should return early from the kernel implementation). Otherwise, attempts to write to this empty tensor would result in heap OOB access. The fix is included in TensorFlow 2.7.0.

Tensorflow is an Open Source Machine Learning Framework. When decoding a tensor from protobuf, TensorFlow might do a null-dereference if attributes of some mutable arguments to some operations are missing from the proto. This is guarded by a `DCHECK`. However, `DCHECK` is a no-op in production builds and an assertion failure in debug builds. In the first case execution proceeds to the dereferencing of the null pointer, whereas in the second case it results in a crash due to the assertion failure. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, and TensorFlow 2.6.3, as these are also affected and still in supported range.

Tensorflow versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2 and 2.4.0 includes a fix for CVE-2020-26271: In affected versions, under certain cases, loading a saved model can result in accessing uninitialized memory while building the computation graph. The MakeEdge function creates an edge between one output tensor of the src node (given by output_index) and the input slot of the dst node (given by input_index). This is only possible if the types of the tensors on both sides coincide, so the function begins by obtaining the corresponding DataType values and comparing these for equality. However, there is no check that the indices point to inside of the arrays they index into. Thus, this can result in accessing data out of bounds of the corresponding heap allocated arrays. In most scenarios, this can manifest as unitialized data access, but if the index points far away from the boundaries of the arrays this can be used to leak addresses from the library.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, and 2.3.1 include a fix for CVE-2020-15206: In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, changing the TensorFlow's "SavedModel" protocol buffer and altering the name of required keys results in segfaults and data corruption while loading the model. This can cause a denial of service in products using "tensorflow-serving" or other inference-as-a-service installments. Fixed were added in commits f760f88b4267d981e13f4b302c437ae800445968 and fcfef195637c6e365577829c4d67681695956e7d. However, this was not enough, as #41097 reported a different failure mode.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2 and 2.2.1 updates its dependency "SQLite" to handle CVE-2020-13630.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, and 2.3.1 include a fix for CVE-2020-15211: In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, saved models in the flatbuffer format use a double indexing scheme: a model has a set of subgraphs, each subgraph has a set of operators and each operator has a set of input/output tensors. The flatbuffer format uses indices for the tensors, indexing into an array of tensors that is owned by the subgraph. This results in a pattern of double array indexing when trying to get the data of each tensor. However, some operators can have some tensors be optional. To handle this scenario, the flatbuffer model uses a negative "-1" value as index for these tensors. This results in special casing during validation at model loading time. Unfortunately, this means that the "-1" index is a valid tensor index for any operator, including those that don't expect optional inputs and including for output tensors. Thus, this allows writing and reading from outside the bounds of heap allocated arrays, although only at a specific offset from the start of these arrays. This results in both read and write gadgets, albeit very limited in scope. The issue was patched in several commits (46d5b0852, 00302787b7, e11f5558, cd31fd0ce, 1970c21, and fff2c83). A potential workaround would be to add a custom "Verifier" to the model loading code to ensure that only operators which accept optional inputs use the "-1" special value and only for the tensors that they expect to be optional. Since this allow-list type approach is error-prone, it's advised upgrading to the patched code.

Affected versions of Tensorflow allow tensors to have a large number of dimensions and each dimension can be as large as desired. However, the total number of elements in a tensor must fit within an 'int64_t'. If an overflow occurs, 'MultiplyWithoutOverflow' would return a negative result. In the majority of TensorFlow codebase this then results in a 'CHECK'-failure. Newer constructs exist which return a 'Status' instead of crashing the binary. This is a similar issue to CVE-2021-29584.

Although `reverse_index_map_t` and `grad_values_t` are accessed in a similar pattern, only `reverse_index_map_t` is validated to be of proper shape. Hence, malicious users can pass a bad `grad_values_t` to trigger an assertion failure in `vec`, causing denial of service in serving installations. The issue is patched in commit 390611e0d45c5793c7066110af37c8514e6a6c54, and is released in TensorFlow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, or 2.3.1."

Tensorflow is an Open Source Machine Learning Framework. A malicious user can cause a denial of service by altering a 'SavedModel' such that any binary op would trigger 'CHECK' failures. This occurs when the protobuf part corresponding to the tensor arguments is modified such that the 'dtype' no longer matches the 'dtype' expected by the op. In that case, calling the templated binary operator for the binary op would receive corrupted data, due to the type confusion involved. If 'Tin' and 'Tout' don't match the type of data in 'out' and 'input_*' tensors then 'flat<*>' would interpret it wrongly. In most cases, this would be a silent failure, but we have noticed scenarios where this results in a 'CHECK' crash, hence a denial of service. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41221: In affected versions, the shape inference code for the 'Cudnn*' operations can be tricked into accessing invalid memory via a heap buffer overflow. This occurs because the ranks of the 'input', 'input_h' and 'input_c' parameters are not validated, but code assumes they have certain values. The fix is included in TensorFlow 2.7.0.

While this is acceptable in testing, in utilities and libraries it is dangerous as a different process can create the file between the check for the filename in 'mktemp' and the actual creation of the file by a subsequent operation (a TOC/TOU type of weakness). In several instances, TensorFlow was supposed to actually create a temporary directory instead of a file. This logic bug is hidden away by the 'mktemp' function usage. It was replaced 'mktemp' with the safer 'mkstemp'/'mkdtemp' functions, according to the usage pattern.

Tensorflow is an Open Source Machine Learning Framework. When decoding a tensor from protobuf, a TensorFlow process can encounter cases where a `CHECK` assertion is invalidated based on user controlled arguments, if the tensors have an invalid `dtype` and 0 elements or an invalid shape. This allows attackers to cause denial of services in TensorFlow processes. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Impact: A recurring instance of CVE-2022-35935 has been observed and addressed. In this case, `SobolSample` is prone to denial of service due to assumed scalar inputs. You can replicate this using the following code in Python:

```python 
import tensorflow as tf 
tf.raw_ops.SobolSample(dim=tf.constant([1,0]), num_results=tf.constant([1]), skip=tf.constant([1])) 
```

Patches: Corrective measures have been taken and the issue has been patched via GitHub commits c65c67f88ad770662e8f191269a907bf2b94b1bf and 02400ea266bd811fc016a848445de1bbff3a23a0. These fixes will be integrated in the forthcoming TensorFlow 2.11 release and will also be added to TensorFlow 2.10.1, 2.9.3, and 2.8.4 as they fall within the supported range. Furthermore, the initial commit will be incorporated into TensorFlow 2.7.4.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, and 2.3.1 include a fix for CVE-2020-15208: In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, when determining the common dimension size of two tensors, TFLite uses a "DCHECK" which is no-op outside of debug compilation modes. Since the function always returns the dimension of the first tensor, malicious attackers can craft cases where this is larger than that of the second tensor. In turn, this would result in reads/writes outside of bounds since the interpreter will wrongly assume that there is enough data in both tensors. The issue was patched in commit 8ee24e7949a203d234489f9da2c5bf45a7d5157d

This occurs because the code assumes that the first node in the pairing (e.g., an 'Enter' node) always exists when encountering the second node (e.g., an 'Exit' node). When this is not the case, 'parent' is 'nullptr' so dereferencing it causes a crash. The fix is included in TensorFlow 2.7.0.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, and 2.3.1 include a fix for CVE-2020-15209: In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, a crafted TFLite model can force a node to have as input a tensor backed by a "nullptr" buffer. This can be achieved by changing a buffer index in the flatbuffer serialization to convert a read-only tensor to a read-write one. The runtime assumes that these buffers are written to before a possible read, hence they are initialized with "nullptr". However, by changing the buffer index for a tensor and implicitly converting that tensor to be a read-write one, as there is nothing in the model that writes to it, we get a null pointer dereference. The issue was patched in commit 0b5662bc.

Tensorflow versions 1.15.3, 2.0.2 and 2.1.1 updates its dependency "Apache Spark" to handle CVE-2018-17190.

TensorFlow 2.7.4, 2.8.3 and 2.9.2 include a fix for CVE-2022-35952: 'CHECK' failures in 'UnbatchGradOp'.
https://github.com/tensorflow/tensorflow/security/advisories/GHSA-h5vq-gw2c-pq47

Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41228: In affected versions, TensorFlow's 'saved_model_cli' tool is vulnerable to a code injection as it calls 'eval' on user supplied strings. This can be used by attackers to run arbitrary code on the plaform where the CLI tool runs. However, given that the tool is always run manually, the impact of this is not severe. The issue has been patched by adding a 'safe' flag which defaults to 'True' and an explicit warning for users.

Tensorflow versions 1.15.3, 2.0.2 and 2.1.1 updates its dependency "SQLite3" to handle CVE-2019-19244.

Tensorflow is an Open Source Machine Learning Framework. The implementation of `AssignOp` can result in copying uninitialized data to a new tensor. This later results in undefined behavior. The implementation has a check that the left hand side of the assignment is initialized (to minimize number of allocations), but does not check that the right hand side is also initialized. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

TensorFlow 2.7.4, 2.8.3 and 2.9.2 include a fix for CVE-2022-35937: OOB read in 'Gather_nd' op in TF Lite.

Tensorflow 1.15 includes a fix for CVE-2019-16778: In TensorFlow before 1.15, a heap buffer overflow in UnsortedSegmentSum can be produced when the Index template argument is int32. In this case data_size and num_segments fields are truncated from int64 to int32 and can produce negative numbers, resulting in accessing out of bounds heap memory. This is unlikely to be exploitable and was detected and fixed internally in TensorFlow 1.15 and 2.0.

Selected versions of TensorFlow are subject to a Denial of Service (DoS) vulnerability due to an issue in the implementation of depthwise operations. This vulnerability arises when a tensor's element count overflows as a result of an assertion failure, triggered by specific inputs and filter sizes in depthwise convolution backpropagation operations. The vulnerability is linked to an incomplete remediation of CVE-2021-41197.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2 and 2.2.1 updates its dependency "SQLite" to handle CVE-2020-13871.

Tensorflow versions 2.5.3, 2.6.3 and 2.7.1 include a fix for CVE-2021-41206: In affected versions, several TensorFlow operations are missing validation for the shapes of the tensor arguments involved in the call. Depending on the API, this can result in undefined behavior and segfault or 'CHECK'-fail related crashes but in some scenarios writes and reads from heap populated arrays are also possible. These issues were discovered internally via tooling while working on improving/testing GPU op determinism. As such, there aren't reproducers and there will be multiple fixes for these issues.

Tensorflow versions 2.6.4, 2.7.2, 2.8.1 and 2.9.0 update 'curl' to v7.83.1 to handle CVE-2022-27778.

Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41198: In affected versions, if 'tf.tile' is called with a large input argument, then the TensorFlow process will crash due to a 'CHECK'-failure caused by an overflow. The number of elements in the output tensor is too much for the 'int64_t' type and the overflow is detected via a 'CHECK' statement. This aborts the process. The fix is included in TensorFlow 2.7.0.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1 include a fix for CVE-2020-15195: In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the implementation of 'SparseFillEmptyRowsGrad' uses a double indexing pattern. It is possible for 'reverse_index_map(i)' to be an index outside of bounds of 'grad_values', thus resulting in a heap buffer overflow.

TensorFlow updates its curl dependency from version 8.2.1 to 8.4.0 to address CVE-2023-38546.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1 include a fix for CVE-2020-15202: In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the 'Shard' API in TensorFlow expects the last argument to be a function taking two 'int64' (i.e., 'long long') arguments. However, there are several places in TensorFlow where a lambda taking 'int' or 'int32' arguments is being used. In these cases, if the amount of work to be parallelized is large enough, integer truncation occurs. Depending on how the two arguments of the lambda are used, this can result in segfaults, read/write outside of heap allocated arrays, stack overflows, or data corruption.

The effect of CVE-2022-35991 was seen once more, where TensorListScatter and TensorListScatterV2 could potentially crash due to non scalar inputs in the element_shape parameter while in eager mode. This issue has been identified and resolved. The issue was identified when the following Python code was executed:

```python 
import tensorflow as tf 
arg_0=tf.random.uniform(shape=(2, 2, 2), dtype=tf.float16, maxval=None) 
arg_1=tf.random.uniform(shape=(2, 2, 2), dtype=tf.int32, maxval=65536) 
arg_2=tf.random.uniform(shape=(2, 2, 2), dtype=tf.int32, maxval=65536) 
arg_3='' 
tf.raw_ops.TensorListScatter(tensor=arg_0, indices=arg_1,  element_shape=arg_2, name=arg_3) 
```

A patch to resolve this issue is available in the GitHub commit bf9932fc907aff0e9e8cccf769e8b00d30fd81a1. This fix will be part of TensorFlow 2.11. Additionally, the commitment will be selected for TensorFlow 2.10.1, 2.9.3, and TensorFlow 2.8.4, as these versions are also known to be affected and still under supported range.

Tensorflow is an Open Source Machine Learning Framework. When decoding PNG images TensorFlow can produce a memory leak if the image is invalid. After calling `png::CommonInitDecode(..., &decode)`, the `decode` value contains allocated buffers which can only be freed by calling `png::CommonFreeDecode(&decode)`. However, several error case in the function implementation invoke the `OP_REQUIRES` macro which immediately terminates the execution of the function, without allowing for the memory free to occur. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Tensorflow is an Open Source Machine Learning Framework. There is a typo in TensorFlow's `SpecializeType` which results in heap OOB read/write. Due to a typo, `arg` is initialized to the `i`th mutable argument in a loop where the loop index is `j`. Hence it is possible to assign to `arg` from outside the vector of arguments. Since this is a mutable proto value, it allows both read and write to outside of bounds data. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, and TensorFlow 2.6.3, as these are also affected and still in supported range.

Tensorflow versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2 and 2.4.0 includes a fix for CVE-2020-26268: In affected versions, the tf.raw_ops.ImmutableConst operation returns a constant tensor created from a memory mapped file which is assumed immutable. However, if the type of the tensor is not an integral type, the operation crashes the Python interpreter as it tries to write to the memory area. If the file is too small, TensorFlow properly returns an error as the memory area has fewer bytes than what is needed for the tensor it creates. However, as soon as there are enough bytes, the above snippet causes a segmentation fault. This is because the allocator used to return the buffer data is not marked as returning an opaque handle since the needed virtual method is not overridden.

Tensorflow 2.11.1 and 2.12.0 include a fix for CVE-2023-25674: Versions prior to 2.12.0 and 2.11.1 have a null pointer error in RandomShuffle with XLA enabled.

Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41195: In affected versions, the implementation of 'tf.math.segment_*' operations results in a 'CHECK'-fail related abort (and denial of service) if a segment id in 'segment_ids' is large. This is similar to CVE-2021-29584 (and similar to other reported vulnerabilities in TensorFlow localized to specific APIs): the implementation (both on CPU and GPU) computes the output shape using 'AddDim'. However, if the number of elements in the tensor overflows an 'int64_t' value, 'AddDim' results in a 'CHECK' failure which provokes a 'std::abort'. Instead, code should use 'AddDimWithStatus'. The fix is included in TensorFlow 2.7.0.

Tensorflow versions 2.5.3, 2.6.3, 2.7.1 and 2.8.0 include a fix for CVE-2022-21727: The implementation of shape inference for 'Dequantize' is vulnerable to an integer overflow weakness. The 'axis' argument can be '-1' (the default value for the optional argument) or any other positive value at most the number of dimensions of the input. Unfortunately, the upper bound is not checked, and, since the code computes 'axis + 1', an attacker can trigger an integer overflow.

Tensorflow is an Open Source Machine Learning Framework. A malicious user can cause a denial of service by altering a `SavedModel` such that assertions in `function.cc` would be falsified and crash the Python interpreter. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Tensorflow versions 1.15.2 and 2.0.1 includes a fix for CVE-2020-5215: In TensorFlow before 1.15.2 and 2.0.1, converting a string (from Python) to a tf.float16 value results in a segmentation fault in eager mode as the format checks for this use case are only in the graph mode. This issue can lead to denial of service in inference/training where a malicious attacker can send a data point which contains a string instead of a tf.float16 value. Similar effects can be obtained by manipulating saved models and checkpoints whereby replacing a scalar tf.float16 value with a scalar string will trigger this issue due to automatic conversions. This can be easily reproduced by tf.constant("hello", tf.float16), if eager execution is enabled.

TensorFlow 2.4.0 includes a fix for CVE-2020-15265: In Tensorflow before version 2.4.0, an attacker can pass an invalid `axis` value to `tf.quantization.quantize_and_dequantize`. This results in accessing a dimension outside the rank of the input tensor in the C++ kernel implementation. However, dim_size only does a DCHECK to validate the argument and then uses it to access the corresponding element of an array. Since in normal builds, `DCHECK`-like macros are no-ops, this results in segfault and access out of bounds of the array. The issue is patched in eccb7ec454e6617738554a255d77f08e60ee0808 and TensorFlow 2.4.0 will be released containing the patch. TensorFlow nightly packages after this commit will also have the issue resolved.

The code assumes that these two arguments define a permutation of NHWC. This can result in uninitialized memory accesses, read outside of bounds and even crashes.

TensorFlow versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2, and 2.4.0 includes a fix for CVE-2020-26266: In affected versions and under certain cases a saved model can trigger use of uninitialized values during code execution. This is caused by having tensor buffers filled with the default value of the type but forgetting to default initialize the quantized floating point types in Eigen.

Tensorflow versions 2.5.3, 2.6.3, 2.7.1 and 2.8.0 include a fix for CVE-2022-21731: The implementation of shape inference for 'ConcatV2' can be used to trigger a denial of service attack via a segfault caused by a type confusion. The 'axis' argument is translated into 'concat_dim' in the 'ConcatShapeHelper' helper function. Then, a value for 'min_rank' is computed based on 'concat_dim'. This is then used to validate that the 'values' tensor has at least the required rank. However, 'WithRankAtLeast' receives the lower bound as a 64-bits value and then compares it against the maximum 32-bits integer value that could be represented. Due to the fact that 'min_rank' is a 32-bits value and the value of 'axis', the 'rank' argument is a negative value, so the error check is bypassed.

Tensorflow versions 2.5.3, 2.6.3, 2.7.1 and 2.8.0 include a fix for CVE-2022-21737: The implementation of '*Bincount' operations allows malicious users to cause denial of service by passing in arguments which would trigger a 'CHECK'-fail. There are several conditions that the input arguments must satisfy. Some are not caught during shape inference and others are not caught during kernel implementation.

Tensorflow versions 2.5.3, 2.6.3, 2.7.1 and 2.8.0 include a fix for CVE-2022-21728: The implementation of shape inference for 'ReverseSequence' does not fully validate the value of 'batch_dim' and can result in a heap OOB read. There is a check to make sure the value of 'batch_dim' does not go over the rank of the input, but there is no check for negative values. Negative dimensions are allowed in some cases to mimic Python's negative indexing (i.e., indexing from the end of the array), however if the value is too negative then the implementation of 'Dim' would access elements before the start of an array.

Tensorflow is an Open Source Machine Learning Framework. Under certain scenarios, Grappler component of TensorFlow can trigger a null pointer dereference. There are 2 places where this can occur, for the same malicious alteration of a `SavedModel` file (fixing the first one would trigger the same dereference in the second place). First, during constant folding, the `GraphDef` might not have the required nodes for the binary operation. If a node is missing, the correposning `mul_*child` would be null, and the dereference in the subsequent line would be incorrect. We have a similar issue during `IsIdentityConsumingSwitch`. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Tensorflow 2.8.4, 2.9.3 and 2.10.1 include a fix for CVE-2022-41894: The reference kernel of the 'CONV_3D_TRANSPOSE' TensorFlow Lite operator wrongly increments the data_ptr when adding the bias to the result. Instead of 'data_ptr += num_channels;' it should be 'data_ptr += output_num_channels;' as if the number of input channels is different than the number of output channels, the wrong result will be returned and a buffer overflow will occur if num_channels > output_num_channels. An attacker can craft a model with a specific number of input channels. It is then possible to write specific values through the bias of the layer outside the bounds of the buffer. This attack only works if the reference kernel resolver is used in the interpreter.

The Grappler component of TensorFlow has a susceptibility to a denial-of-service through a CHECK-failure during constant folding. This issue arises from the output_prop tensor, which has a user-controlled shape and can trigger one of the PartialTensorShape constructor's CHECKs. This flaw has been designated as TFSA-2021-198.

The problem has been addressed and rectified in the GitHub commit be7b286d40bc68cb0b56f702186cc4837d508058, which will be incorporated in TensorFlow 2.8.0. This fix will also be applied to TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3 versions as they too are within the affected and presently supported range.

Since the cropping parameters are user controlled, a malicious person can trigger undefined behavior. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1 include a fix for CVE-2020-15207: In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, to mimic Python's indexing with negative values, TFLite uses 'ResolveAxis' to convert negative values to positive indices. However, the only check that the converted index is now valid is only present in debug builds. If the 'DCHECK' does not trigger, then code execution moves ahead with a negative index. This, in turn, results in accessing data out of bounds which results in segfaults and/or data corruption.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1 include a fix for CVE-2020-15205: In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the 'data_splits' argument of 'tf.raw_ops.StringNGrams' lacks validation. This allows a user to pass values that can cause heap overflow errors and even leak contents of memory In the linked code snippet, all the binary strings after 'ee ff' are contents from the memory stack. Since these can contain return addresses, this data leak can be used to defeat ASLR.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1 include a fix for CVE-2020-15190: In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the "tf.raw_ops.Switch" operation takes as input a tensor and a boolean and outputs two tensors. Depending on the boolean value, one of the tensors is exactly the input tensor whereas the other one should be an empty tensor. However, the eager runtime traverses all tensors in the output. Since only one of the tensors is defined, the other one is "nullptr", hence we are binding a reference to "nullptr". This is undefined behavior and reported as an error if compiling with "-fsanitize=null". In this case, this results in a segmentation fault The issue was patched in commit da8558533d925694483d2c136a9220d6d49d843c

Tensorflow is an Open Source Machine Learning Framework. Under certain scenarios, TensorFlow can fail to specialize a type during shape inference. This case is covered by the 'DCHECK' function however, 'DCHECK' is a no-op in production builds and an assertion failure in debug builds. In the first case execution proceeds to the 'ValueOrDie' line. This results in an assertion failure as 'ret' contains an error 'Status', not a value. In the second case we also get a crash due to the assertion failure. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, and TensorFlow 2.6.3, as these are also affected and still in supported range.

Tensorflow versions 2.5.3, 2.6.3 and 2.7.1 include a fix for CVE-2021-41208: In affected versions, the code for boosted trees in TensorFlow is still missing validation. As a result, attackers can trigger denial of service (via dereferencing 'nullptr's or via 'CHECK'-failures) as well as abuse undefined behavior (binding references to 'nullptr's). An attacker can also read and write from heap buffers, depending on the API that gets used and the arguments that are passed to the call. Given that the boosted trees implementation in TensorFlow is unmaintained, it is recommend to no longer use these APIs. TensorFlow's boosted trees APIs will be deprecated in subsequent releases.

Tensorflow is an Open Source Machine Learning Framework. When decoding a tensor from protobuf, TensorFlow might do a null-dereference if attributes of some mutable arguments to some operations are missing from the proto. This is guarded by a `DCHECK`. However, `DCHECK` is a no-op in production builds and an assertion failure in debug builds. In the first case execution proceeds to the dereferencing of the null pointer, whereas in the second case it results in a crash due to the assertion failure.

Tensorflow versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2 and 2.4.0 includes a fix for CVE-2020-26271: In affected versions, under certain cases, loading a saved model can result in accessing uninitialized memory while building the computation graph. The MakeEdge function creates an edge between one output tensor of the src node (given by output_index) and the input slot of the dst node (given by input_index). This is only possible if the types of the tensors on both sides coincide, so the function begins by obtaining the corresponding DataType values and comparing these for equality. However, there is no check that the indices point to inside of the arrays they index into. Thus, this can result in accessing data out of bounds of the corresponding heap allocated arrays. In most scenarios, this can manifest as unitialized data access, but if the index points far away from the boundaries of the arrays this can be used to leak addresses from the library.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, and 2.3.1 include a fix for CVE-2020-15206: In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, changing the TensorFlow's "SavedModel" protocol buffer and altering the name of required keys results in segfaults and data corruption while loading the model. This can cause a denial of service in products using "tensorflow-serving" or other inference-as-a-service installments. Fixed were added in commits f760f88b4267d981e13f4b302c437ae800445968 and fcfef195637c6e365577829c4d67681695956e7d. However, this was not enough, as #41097 reported a different failure mode. The issue was finally patched in commit df095206f25471e864a8e63a0f1caef53a0e3a6

Tensorflow versions 1.15.4, 2.0.3, 2.1.2 and 2.2.1 updates its dependency "SQLite" to handle CVE-2020-13630.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, and 2.3.1 include a fix for CVE-2020-15211: In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, saved models in the flatbuffer format use a double indexing scheme: a model has a set of subgraphs, each subgraph has a set of operators and each operator has a set of input/output tensors. The flatbuffer format uses indices for the tensors, indexing into an array of tensors that is owned by the subgraph. This results in a pattern of double array indexing when trying to get the data of each tensor. However, some operators can have some tensors be optional. To handle this scenario, the flatbuffer model uses a negative "-1" value as index for these tensors. This results in special casing during validation at model loading time. Unfortunately, this means that the "-1" index is a valid tensor index for any operator, including those that don't expect optional inputs and including for output tensors. Thus, this allows writing and reading from outside the bounds of heap allocated arrays, although only at a specific offset from the start of these arrays. This results in both read and write gadgets, albeit very limited in scope. The issue was patched in several commits (46d5b0852, 00302787b7, e11f5558, cd31fd0ce, 1970c21, and fff2c83). A potential workaround would be to add a custom "Verifier" to the model loading code to ensure that only operators which accept optional inputs use the "-1" special value and only for the tensors that they expect to be optional. Since this allow-list type approach is error-prone, it's advised upgrading to the patched code.

Affected versions of Tensorflow allow tensors to have a large number of dimensions and each dimension can be as large as desired. However, the total number of elements in a tensor must fit within an 'int64_t'. If an overflow occurs, 'MultiplyWithoutOverflow' would return a negative result. In the majority of TensorFlow codebase this then results in a 'CHECK'-failure. Newer constructs exist which return a 'Status' instead of crashing the binary. This is a similar issue to CVE-2021-29584.

Tensorflow 2.8.4, 2.9.3 and 2.10.1 include a fix for CVE-2022-41880: When the 'BaseCandidateSamplerOp' function receives a value in 'true_classes' larger than 'range_max', a heap oob read occurs.

TensorFlow 2.4.0 includes a fix for CVE-2020-15194: In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the `SparseFillEmptyRowsGrad` implementation has incomplete validation of the shapes of its arguments. Although `reverse_index_map_t` and `grad_values_t` are accessed in a similar pattern, only `reverse_index_map_t` is validated to be of proper shape. Hence, malicious users can pass a bad `grad_values_t` to trigger an assertion failure in `vec`, causing denial of service in serving installations. The issue is patched in commit 390611e0d45c5793c7066110af37c8514e6a6c54, and is released in TensorFlow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, or 2.3.1."

Tensorflow is an Open Source Machine Learning Framework. A malicious user can cause a denial of service by altering a 'SavedModel' such that any binary op would trigger 'CHECK' failures. This occurs when the protobuf part corresponding to the tensor arguments is modified such that the 'dtype' no longer matches the 'dtype' expected by the op. In that case, calling the templated binary operator for the binary op would receive corrupted data, due to the type confusion involved. If 'Tin' and 'Tout' don't match the type of data in 'out' and 'input_*' tensors then 'flat<*>' would interpret it wrongly. In most cases, this would be a silent failure, but we have noticed scenarios where this results in a 'CHECK' crash, hence a denial of service. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41221: In affected versions, the shape inference code for the 'Cudnn*' operations can be tricked into accessing invalid memory via a heap buffer overflow.

While this is acceptable in testing, in utilities and libraries it is dangerous as a different process can create the file between the check for the filename in 'mktemp' and the actual creation of the file by a subsequent operation (a TOC/TOU type of weakness). In several instances, TensorFlow was supposed to actually create a temporary directory instead of a file. This logic bug is hidden away by the 'mktemp' function usage. It was replaced 'mktemp' with the safer 'mkstemp'/'mkdtemp' functions, according to the usage pattern.

Tensorflow is an Open Source Machine Learning Framework. When decoding a tensor from protobuf, a TensorFlow process can encounter cases where a `CHECK` assertion is invalidated based on user controlled arguments, if the tensors have an invalid `dtype` and 0 elements or an invalid shape. This allows attackers to cause denial of services in TensorFlow processes. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Impact: A recurring instance of CVE-2022-35935 has been observed and addressed. In this case, `SobolSample` is prone to denial of service due to assumed scalar inputs. You can replicate this using the following code in Python:

```python 
import tensorflow as tf 
tf.raw_ops.SobolSample(dim=tf.constant([1,0]), num_results=tf.constant([1]), skip=tf.constant([1])) 
```

Patches: Corrective measures have been taken and the issue has been patched via GitHub commits c65c67f88ad770662e8f191269a907bf2b94b1bf and 02400ea266bd811fc016a848445de1bbff3a23a0. These fixes will be integrated in the forthcoming TensorFlow 2.11 release and will also be added to TensorFlow 2.10.1, 2.9.3, and 2.8.4 as they fall within the supported range. Furthermore, the initial commit will be incorporated into TensorFlow 2.7.4.

Tensorflow versions 2.3.2, 2.2.2, 2.1.3, 2.0.4 and 1.15.5 updates its dependency "Libjpeg-turbo" to handle CVE-2020-13790.

Tensorflow is an Open Source Machine Learning Framework. TensorFlow is vulnerable to a heap OOB write in `Grappler`. The `set_output` function writes to an array at the specified index. Hence, this gives a malicious user a write primitive. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41213: In affected versions, the code behind 'tf.function' API can be made to deadlock when two 'tf.function' decorated Python functions are mutually recursive. This occurs due to using a non-reentrant 'Lock' Python object. Loading any model which contains mutually recursive functions is vulnerable. An attacker can cause denial of service by causing users to load such models and calling a recursive 'tf.function', although this is not a frequent scenario.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, and 2.3.1 include a fix for CVE-2020-15208: In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, when determining the common dimension size of two tensors, TFLite uses a "DCHECK" which is no-op outside of debug compilation modes. Since the function always returns the dimension of the first tensor, malicious attackers can craft cases where this is larger than that of the second tensor. In turn, this would result in reads/writes outside of bounds since the interpreter will wrongly assume that there is enough data in both tensors. The issue was patched in commit 8ee24e7949a203d234489f9da2c5bf45a7d5157d

Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41223: In affected versions, the implementation of 'FusedBatchNorm' kernels is vulnerable to a heap OOB access. The fix is included in TensorFlow 2.7.0.

TensorFlow is an open source platform for machine learning. An input 'sparse_matrix' that is not a matrix with a shape with rank 0 will trigger a 'CHECK' fail in 'tf.raw_ops.SparseMatrixNNZ'. We have patched the issue in GitHub commit f856d02e5322821aad155dad9b3acab1e9f5d693. The fix will be included in TensorFlow 2.11. We will also cherrypick this commit on TensorFlow 2.10.1, 2.9.3, and TensorFlow 2.8.4, as these are also affected and still in supported range.

Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41217: In affected versions, the process of building the control flow graph for a TensorFlow model is vulnerable to a null pointer exception when nodes that should be paired are not. This occurs because the code assumes that the first node in the pairing (e.g., an 'Enter' node) always exists when encountering the second node (e.g., an 'Exit' node). When this is not the case, 'parent' is 'nullptr' so dereferencing it causes a crash. The fix is included in TensorFlow 2.7.0.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, and 2.3.1 include a fix for CVE-2020-15209: In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, a crafted TFLite model can force a node to have as input a tensor backed by a "nullptr" buffer. This can be achieved by changing a buffer index in the flatbuffer serialization to convert a read-only tensor to a read-write one. The runtime assumes that these buffers are written to before a possible read, hence they are initialized with "nullptr". However, by changing the buffer index for a tensor and implicitly converting that tensor to be a read-write one, as there is nothing in the model that writes to it, we get a null pointer dereference. The issue was patched in commit 0b5662bc.

Tensorflow versions 1.15.3, 2.0.2 and 2.1.1 updates its dependency "Apache Spark" to handle CVE-2018-17190.

Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41228: In affected versions, TensorFlow's 'saved_model_cli' tool is vulnerable to a code injection as it calls 'eval' on user supplied strings. This can be used by attackers to run arbitrary code on the plaform where the CLI tool runs. However, given that the tool is always run manually, the impact of this is not severe. The issue has been patched by adding a 'safe' flag which defaults to 'True' and an explicit warning for users.

Tensorflow versions 1.15.3, 2.0.2 and 2.1.1 updates its dependency "SQLite3" to handle CVE-2019-19244.

Tensorflow is an Open Source Machine Learning Framework. The implementation of `AssignOp` can result in copying uninitialized data to a new tensor. This later results in undefined behavior. The implementation has a check that the left hand side of the assignment is initialized (to minimize number of allocations), but does not check that the right hand side is also initialized. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Tensorflow 1.15 includes a fix for CVE-2019-16778: In TensorFlow before 1.15, a heap buffer overflow in UnsortedSegmentSum can be produced when the Index template argument is int32. In this case data_size and num_segments fields are truncated from int64 to int32 and can produce negative numbers, resulting in accessing out of bounds heap memory. This is unlikely to be exploitable and was detected and fixed internally in TensorFlow 1.15 and 2.0.

Selected versions of TensorFlow are subject to a Denial of Service (DoS) vulnerability due to an issue in the implementation of depthwise operations. This vulnerability arises when a tensor's element count overflows as a result of an assertion failure, triggered by specific inputs and filter sizes in depthwise convolution backpropagation operations. The vulnerability is linked to an incomplete remediation of CVE-2021-41197.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2 and 2.2.1 updates its dependency "SQLite" to handle CVE-2020-13871.

Tensorflow versions 2.5.3, 2.6.3 and 2.7.1 include a fix for CVE-2021-41206: In affected versions, several TensorFlow operations are missing validation for the shapes of the tensor arguments involved in the call. Depending on the API, this can result in undefined behavior and segfault or 'CHECK'-fail related crashes but in some scenarios writes and reads from heap populated arrays are also possible. These issues were discovered internally via tooling while working on improving/testing GPU op determinism. As such, there aren't reproducers and there will be multiple fixes for these issues.

TensorFlow updates its curl dependency from version 8.2.1 to 8.4.0 to address CVE-2023-38546.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1 include a fix for CVE-2020-15202: In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the 'Shard' API in TensorFlow expects the last argument to be a function taking two 'int64' (i.e., 'long long') arguments. However, there are several places in TensorFlow where a lambda taking 'int' or 'int32' arguments is being used. In these cases, if the amount of work to be parallelized is large enough, integer truncation occurs. Depending on how the two arguments of the lambda are used, this can result in segfaults, read/write outside of heap allocated arrays, stack overflows, or data corruption.

The effect of CVE-2022-35991 was seen once more, where TensorListScatter and TensorListScatterV2 could potentially crash due to non scalar inputs in the element_shape parameter while in eager mode. This issue has been identified and resolved. The issue was identified when the following Python code was executed:

```python 
import tensorflow as tf 
arg_0=tf.random.uniform(shape=(2, 2, 2), dtype=tf.float16, maxval=None) 
arg_1=tf.random.uniform(shape=(2, 2, 2), dtype=tf.int32, maxval=65536) 
arg_2=tf.random.uniform(shape=(2, 2, 2), dtype=tf.int32, maxval=65536) 
arg_3='' 
tf.raw_ops.TensorListScatter(tensor=arg_0, indices=arg_1,  element_shape=arg_2, name=arg_3) 
```

A patch to resolve this issue is available in the GitHub commit bf9932fc907aff0e9e8cccf769e8b00d30fd81a1. This fix will be part of TensorFlow 2.11. Additionally, the commitment will be selected for TensorFlow 2.10.1, 2.9.3, and TensorFlow 2.8.4, as these versions are also known to be affected and still under supported range.

Tensorflow is an Open Source Machine Learning Framework. When decoding PNG images TensorFlow can produce a memory leak if the image is invalid. After calling `png::CommonInitDecode(..., &decode)`, the `decode` value contains allocated buffers which can only be freed by calling `png::CommonFreeDecode(&decode)`. However, several error case in the function implementation invoke the `OP_REQUIRES` macro which immediately terminates the execution of the function, without allowing for the memory free to occur. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Tensorflow is an Open Source Machine Learning Framework. There is a typo in TensorFlow's `SpecializeType` which results in heap OOB read/write. Due to a typo, `arg` is initialized to the `i`th mutable argument in a loop where the loop index is `j`. Hence it is possible to assign to `arg` from outside the vector of arguments. Since this is a mutable proto value, it allows both read and write to outside of bounds data. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, and TensorFlow 2.6.3, as these are also affected and still in supported range.

Tensorflow versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2 and 2.4.0 includes a fix for CVE-2020-26268: In affected versions, the tf.raw_ops.ImmutableConst operation returns a constant tensor created from a memory mapped file which is assumed immutable. However, if the type of the tensor is not an integral type, the operation crashes the Python interpreter as it tries to write to the memory area. If the file is too small, TensorFlow properly returns an error as the memory area has fewer bytes than what is needed for the tensor it creates. However, as soon as there are enough bytes, the above snippet causes a segmentation fault. This is because the allocator used to return the buffer data is not marked as returning an opaque handle since the needed virtual method is not overridden.

Tensorflow 2.11.1 and 2.12.0 include a fix for CVE-2023-25674: Versions prior to 2.12.0 and 2.11.1 have a null pointer error in RandomShuffle with XLA enabled.

Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41195: In affected versions, the implementation of 'tf.math.segment_*' operations results in a 'CHECK'-fail related abort (and denial of service) if a segment id in 'segment_ids' is large. This is similar to CVE-2021-29584 (and similar to other reported vulnerabilities in TensorFlow localized to specific APIs): the implementation (both on CPU and GPU) computes the output shape using 'AddDim'. However, if the number of elements in the tensor overflows an 'int64_t' value, 'AddDim' results in a 'CHECK' failure which provokes a 'std::abort'. Instead, code should use 'AddDimWithStatus'. The fix is included in TensorFlow 2.7.0.

Tensorflow versions 2.5.3, 2.6.3, 2.7.1 and 2.8.0 include a fix for CVE-2022-21727: The implementation of shape inference for 'Dequantize' is vulnerable to an integer overflow weakness. The 'axis' argument can be '-1' (the default value for the optional argument) or any other positive value at most the number of dimensions of the input. Unfortunately, the upper bound is not checked, and, since the code computes 'axis + 1', an attacker can trigger an integer overflow.

Tensorflow is an Open Source Machine Learning Framework. A malicious user can cause a denial of service by altering a `SavedModel` such that assertions in `function.cc` would be falsified and crash the Python interpreter. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Tensorflow versions 1.15.2 and 2.0.1 includes a fix for CVE-2020-5215: In TensorFlow before 1.15.2 and 2.0.1, converting a string (from Python) to a tf.float16 value results in a segmentation fault in eager mode as the format checks for this use case are only in the graph mode. This issue can lead to denial of service in inference/training where a malicious attacker can send a data point which contains a string instead of a tf.float16 value. Similar effects can be obtained by manipulating saved models and checkpoints whereby replacing a scalar tf.float16 value with a scalar string will trigger this issue due to automatic conversions. This can be easily reproduced by tf.constant("hello", tf.float16), if eager execution is enabled.

TensorFlow 2.4.0 includes a fix for CVE-2020-15265: In Tensorflow before version 2.4.0, an attacker can pass an invalid `axis` value to `tf.quantization.quantize_and_dequantize`. This results in accessing a dimension outside the rank of the input tensor in the C++ kernel implementation. However, dim_size only does a DCHECK to validate the argument and then uses it to access the corresponding element of an array. Since in normal builds, `DCHECK`-like macros are no-ops, this results in segfault and access out of bounds of the array. The issue is patched in eccb7ec454e6617738554a255d77f08e60ee0808 and TensorFlow 2.4.0 will be released containing the patch. TensorFlow nightly packages after this commit will also have the issue resolved.

Tensorflow versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2 and 2.4.0 includes a fix for CVE-2020-26267: In affected versions, the tf.raw_ops.DataFormatVecPermute API does not validate the src_format and dst_format attributes. The code assumes that these two arguments define a permutation of NHWC. This can result in uninitialized memory accesses, read outside of bounds and even crashes.

TensorFlow versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2, and 2.4.0 includes a fix for CVE-2020-26266: In affected versions and under certain cases a saved model can trigger use of uninitialized values during code execution. This is caused by having tensor buffers filled with the default value of the type but forgetting to default initialize the quantized floating point types in Eigen.

Tensorflow versions 2.5.3, 2.6.3, 2.7.1 and 2.8.0 include a fix for CVE-2022-21731: The implementation of shape inference for 'ConcatV2' can be used to trigger a denial of service attack via a segfault caused by a type confusion. The 'axis' argument is translated into 'concat_dim' in the 'ConcatShapeHelper' helper function. Then, a value for 'min_rank' is computed based on 'concat_dim'. This is then used to validate that the 'values' tensor has at least the required rank. However, 'WithRankAtLeast' receives the lower bound as a 64-bits value and then compares it against the maximum 32-bits integer value that could be represented. Due to the fact that 'min_rank' is a 32-bits value and the value of 'axis', the 'rank' argument is a negative value, so the error check is bypassed.

Tensorflow versions 2.5.3, 2.6.3, 2.7.1 and 2.8.0 include a fix for CVE-2022-21737: The implementation of '*Bincount' operations allows malicious users to cause denial of service by passing in arguments which would trigger a 'CHECK'-fail. There are several conditions that the input arguments must satisfy. Some are not caught during shape inference and others are not caught during kernel implementation.

There are 2 places where this can occur, for the same malicious alteration of a `SavedModel` file (fixing the first one would trigger the same dereference in the second place). First, during constant folding, the `GraphDef` might not have the required nodes for the binary operation. If a node is missing, the correposning `mul_*child` would be null, and the dereference in the subsequent line would be incorrect. We have a similar issue during `IsIdentityConsumingSwitch`. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1 include a fix for CVE-2020-15210: In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, if a TFLite saved model uses the same tensor as both input and output of an operator, then, depending on the operator, we can observe a segmentation fault or just memory corruption.

Tensorflow 2.8.4, 2.9.3 and 2.10.1 include a fix for CVE-2022-41894: The reference kernel of the 'CONV_3D_TRANSPOSE' TensorFlow Lite operator wrongly increments the data_ptr when adding the bias to the result. Instead of 'data_ptr += num_channels;' it should be 'data_ptr += output_num_channels;' as if the number of input channels is different than the number of output channels, the wrong result will be returned and a buffer overflow will occur if num_channels > output_num_channels. An attacker can craft a model with a specific number of input channels. It is then possible to write specific values through the bias of the layer outside the bounds of the buffer. This attack only works if the reference kernel resolver is used in the interpreter.

The Grappler component of TensorFlow has a susceptibility to a denial-of-service through a CHECK-failure during constant folding. This issue arises from the output_prop tensor, which has a user-controlled shape and can trigger one of the PartialTensorShape constructor's CHECKs. This flaw has been designated as TFSA-2021-198.

The problem has been addressed and rectified in the GitHub commit be7b286d40bc68cb0b56f702186cc4837d508058, which will be incorporated in TensorFlow 2.8.0.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1 include a fix for CVE-2020-15207: In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, to mimic Python's indexing with negative values, TFLite uses 'ResolveAxis' to convert negative values to positive indices. However, the only check that the converted index is now valid is only present in debug builds. If the 'DCHECK' does not trigger, then code execution moves ahead with a negative index. This, in turn, results in accessing data out of bounds which results in segfaults and/or data corruption.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1 include a fix for CVE-2020-15190: In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the "tf.raw_ops.Switch" operation takes as input a tensor and a boolean and outputs two tensors. Depending on the boolean value, one of the tensors is exactly the input tensor whereas the other one should be an empty tensor. However, the eager runtime traverses all tensors in the output. Since only one of the tensors is defined, the other one is "nullptr", hence we are binding a reference to "nullptr". This is undefined behavior and reported as an error if compiling with "-fsanitize=null".

Tensorflow is an Open Source Machine Learning Framework. Under certain scenarios, TensorFlow can fail to specialize a type during shape inference. This case is covered by the 'DCHECK' function however, 'DCHECK' is a no-op in production builds and an assertion failure in debug builds. In the first case execution proceeds to the 'ValueOrDie' line. This results in an assertion failure as 'ret' contains an error 'Status', not a value. In the second case we also get a crash due to the assertion failure. The fix will be included in TensorFlow 2.8.0.

Tensorflow versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2 and 2.4.0 includes a fix for CVE-2020-26270: In affected versions, running an LSTM/GRU model where the LSTM/GRU layer receives an input with zero-length results in a CHECK failure when using the CUDA backend. This can result in a query-of-death vulnerability, via denial of service, if users can control the input to the layer.

Tensorflow versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2 and 2.4.0 includes a fix for CVE-2020-26271: In affected versions, under certain cases, loading a saved model can result in accessing uninitialized memory while building the computation graph. The MakeEdge function creates an edge between one output tensor of the src node (given by output_index) and the input slot of the dst node (given by input_index). This is only possible if the types of the tensors on both sides coincide, so the function begins by obtaining the corresponding DataType values and comparing these for equality. However, there is no check that the indices point to inside of the arrays they index into. Thus, this can result in accessing data out of bounds of the corresponding heap allocated arrays. In most scenarios, this can manifest as unitialized data access, but if the index points far away from the boundaries of the arrays this can be used to leak addresses from the library.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, and 2.3.1 include a fix for CVE-2020-15206: In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, changing the TensorFlow's "SavedModel" protocol buffer and altering the name of required keys results in segfaults and data corruption while loading the model. This can cause a denial of service in products using "tensorflow-serving" or other inference-as-a-service installments. Fixed were added in commits f760f88b4267d981e13f4b302c437ae800445968 and fcfef195637c6e365577829c4d67681695956e7d. However, this was not enough, as #41097 reported a different failure mode. The issue was finally patched in commit df095206f25471e864a8e63a0f1caef53a0e3a6

Tensorflow versions 1.15.4, 2.0.3, 2.1.2 and 2.2.1 updates its dependency "SQLite" to handle CVE-2020-13630.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, and 2.3.1 include a fix for CVE-2020-15211: In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, saved models in the flatbuffer format use a double indexing scheme: a model has a set of subgraphs, each subgraph has a set of operators and each operator has a set of input/output tensors. The flatbuffer format uses indices for the tensors, indexing into an array of tensors that is owned by the subgraph. This results in a pattern of double array indexing when trying to get the data of each tensor. However, some operators can have some tensors be optional. To handle this scenario, the flatbuffer model uses a negative "-1" value as index for these tensors. This results in special casing during validation at model loading time. Unfortunately, this means that the "-1" index is a valid tensor index for any operator, including those that don't expect optional inputs and including for output tensors. Thus, this allows writing and reading from outside the bounds of heap allocated arrays, although only at a specific offset from the start of these arrays. This results in both read and write gadgets, albeit very limited in scope. The issue was patched in several commits (46d5b0852, 00302787b7, e11f5558, cd31fd0ce, 1970c21, and fff2c83). A potential workaround would be to add a custom "Verifier" to the model loading code to ensure that only operators which accept optional inputs use the "-1" special value and only for the tensors that they expect to be optional. Since this allow-list type approach is error-prone, it's advised upgrading to the patched code.

Affected versions of Tensorflow allow tensors to have a large number of dimensions and each dimension can be as large as desired. However, the total number of elements in a tensor must fit within an 'int64_t'. If an overflow occurs, 'MultiplyWithoutOverflow' would return a negative result. In the majority of TensorFlow codebase this then results in a 'CHECK'-failure. Newer constructs exist which return a 'Status' instead of crashing the binary. This is a similar issue to CVE-2021-29584.

Tensorflow 2.8.4, 2.9.3 and 2.10.1 include a fix for CVE-2022-41880: When the 'BaseCandidateSamplerOp' function receives a value in 'true_classes' larger than 'range_max', a heap oob read occurs.

Although `reverse_index_map_t` and `grad_values_t` are accessed in a similar pattern, only `reverse_index_map_t` is validated to be of proper shape. Hence, malicious users can pass a bad `grad_values_t` to trigger an assertion failure in `vec`, causing denial of service in serving installations. The issue is patched in commit 390611e0d45c5793c7066110af37c8514e6a6c54, and is released in TensorFlow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, or 2.3.1."

Tensorflow is an Open Source Machine Learning Framework. A malicious user can cause a denial of service by altering a 'SavedModel' such that any binary op would trigger 'CHECK' failures. This occurs when the protobuf part corresponding to the tensor arguments is modified such that the 'dtype' no longer matches the 'dtype' expected by the op. In that case, calling the templated binary operator for the binary op would receive corrupted data, due to the type confusion involved. If 'Tin' and 'Tout' don't match the type of data in 'out' and 'input_*' tensors then 'flat<*>' would interpret it wrongly. In most cases, this would be a silent failure, but we have noticed scenarios where this results in a 'CHECK' crash, hence a denial of service. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2 and 2.2.1 update its dependency "SQLite" to handle CVE-2020-11655.

Tensorflow is an Open Source Machine Learning Framework. When decoding a tensor from protobuf, a TensorFlow process can encounter cases where a `CHECK` assertion is invalidated based on user controlled arguments, if the tensors have an invalid `dtype` and 0 elements or an invalid shape. This allows attackers to cause denial of services in TensorFlow processes. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Impact: A recurring instance of CVE-2022-35935 has been observed and addressed. In this case, `SobolSample` is prone to denial of service due to assumed scalar inputs. You can replicate this using the following code in Python:

```python 
import tensorflow as tf 
tf.raw_ops.SobolSample(dim=tf.constant([1,0]), num_results=tf.constant([1]), skip=tf.constant([1])) 
```

Patches: Corrective measures have been taken and the issue has been patched via GitHub commits c65c67f88ad770662e8f191269a907bf2b94b1bf and 02400ea266bd811fc016a848445de1bbff3a23a0. These fixes will be integrated in the forthcoming TensorFlow 2.11 release and will also be added to TensorFlow 2.10.1, 2.9.3, and 2.8.4 as they fall within the supported range. Furthermore, the initial commit will be incorporated into TensorFlow 2.7.4.

Tensorflow is an Open Source Machine Learning Framework. TensorFlow is vulnerable to a heap OOB write in `Grappler`. The `set_output` function writes to an array at the specified index. Hence, this gives a malicious user a write primitive. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41213: In affected versions, the code behind 'tf.function' API can be made to deadlock when two 'tf.function' decorated Python functions are mutually recursive. This occurs due to using a non-reentrant 'Lock' Python object. Loading any model which contains mutually recursive functions is vulnerable. An attacker can cause denial of service by causing users to load such models and calling a recursive 'tf.function', although this is not a frequent scenario.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, and 2.3.1 include a fix for CVE-2020-15208: In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, when determining the common dimension size of two tensors, TFLite uses a "DCHECK" which is no-op outside of debug compilation modes. Since the function always returns the dimension of the first tensor, malicious attackers can craft cases where this is larger than that of the second tensor. In turn, this would result in reads/writes outside of bounds since the interpreter will wrongly assume that there is enough data in both tensors. The issue was patched in commit 8ee24e7949a203d234489f9da2c5bf45a7d5157d

Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41223: In affected versions, the implementation of 'FusedBatchNorm' kernels is vulnerable to a heap OOB access. The fix is included in TensorFlow 2.7.0.

Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41217: In affected versions, the process of building the control flow graph for a TensorFlow model is vulnerable to a null pointer exception when nodes that should be paired are not. This occurs because the code assumes that the first node in the pairing (e.g., an 'Enter' node) always exists when encountering the second node (e.g., an 'Exit' node). When this is not the case, 'parent' is 'nullptr' so dereferencing it causes a crash. The fix is included in TensorFlow 2.7.0.

Tensorflow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, and 2.3.1 include a fix for CVE-2020-15209: In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, a crafted TFLite model can force a node to have as input a tensor backed by a "nullptr" buffer. This can be achieved by changing a buffer index in the flatbuffer serialization to convert a read-only tensor to a read-write one. The runtime assumes that these buffers are written to before a possible read, hence they are initialized with "nullptr". However, by changing the buffer index for a tensor and implicitly converting that tensor to be a read-write one, as there is nothing in the model that writes to it, we get a null pointer dereference. The issue was patched in commit 0b5662bc.

Tensorflow versions 1.15.3, 2.0.2 and 2.1.1 updates its dependency "Apache Spark" to handle CVE-2018-17190.

This can be used by attackers to run arbitrary code on the plaform where the CLI tool runs. However, given that the tool is always run manually, the impact of this is not severe. The issue has been patched by adding a 'safe' flag which defaults to 'True' and an explicit warning for users.

Tensorflow versions 1.15.3, 2.0.2 and 2.1.1 updates its dependency "SQLite3" to handle CVE-2019-19244.

Tensorflow is an Open Source Machine Learning Framework. The implementation of `AssignOp` can result in copying uninitialized data to a new tensor. This later results in undefined behavior. The implementation has a check that the left hand side of the assignment is initialized (to minimize number of allocations), but does not check that the right hand side is also initialized. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Selected versions of TensorFlow are subject to a Denial of Service (DoS) vulnerability due to an issue in the implementation of depthwise operations. This vulnerability arises when a tensor's element count overflows as a result of an assertion failure, triggered by specific inputs and filter sizes in depthwise convolution backpropagation operations. The vulnerability is linked to an incomplete remediation of CVE-2021-41197.

Tensorflow versions 2.5.3, 2.6.3 and 2.7.1 include a fix for CVE-2021-41206: In affected versions, several TensorFlow operations are missing validation for the shapes of the tensor arguments involved in the call. Depending on the API, this can result in undefined behavior and segfault or 'CHECK'-fail related crashes but in some scenarios writes and reads from heap populated arrays are also possible. These issues were discovered internally via tooling while working on improving/testing GPU op determinism. As such, there aren't reproducers and there will be multiple fixes for these issues.

However, there are several places in TensorFlow where a lambda taking 'int' or 'int32' arguments is being used. In these cases, if the amount of work to be parallelized is large enough, integer truncation occurs. Depending on how the two arguments of the lambda are used, this can result in segfaults, read/write outside of heap allocated arrays, stack overflows, or data corruption.

Tensorflow 2.8.4, 2.9.3 and 2.10.1 include a fix for CVE-2022-41889: If a list of quantized tensors is assigned to an attribute, the pywrap code fails to parse the tensor and returns a 'nullptr', which is not caught. An example can be seen in 'tf.compat.v1.extract_volume_patches' by passing in quantized tensors as input 'ksizes'.

Tensorflow versions 1.15.3, 2.0.2 and 2.1.1 update its dependency "Apache Spark" to handle CVE-2018-11770.

Tensorflow 2.8.4, 2.9.3 and 2.10.1 include a fix for CVE-2022-41896: If 'ThreadUnsafeUnigramCandidateSampler' is given input 'filterbank_channel_count' greater than the allowed max size, TensorFlow will crash.

Tensorflow versions 2.4.4, 2.5.2 and 2.6.1 include a fix for CVE-2021-41201: In affected versions, during execution, 'EinsumHelper::ParseEquation()' is supposed to set the flags in 'input_has_ellipsis' vector and '*output_has_ellipsis' boolean to indicate whether there is ellipsis in the corresponding inputs and output. However, the code only changes these flags to 'true' and never assigns 'false'. This results in unitialized variable access if callers assume that 'EinsumHelper::ParseEquation()' always sets these flags. The fix is included in TensorFlow 2.7.0.
