pyup-update-pymongo-3.10.1-to-4.6.2
1 year, 6 months ago
Update pymongo from 3.10.1 to 4.6.2
tornado 6.0.3 and cryptography 2.8 have known security vulnerabilities.
| Package | Installed | Affected | Info |
|---|---|---|---|
| tornado | 6.0.3 | <=6.4.0 |
show When Tornado receives a request with two Transfer-Encoding: chunked headers, it ignores them both. This enables request smuggling when Tornado is deployed behind a proxy server that emits such requests. Pound does this. |
| tornado | 6.0.3 | <6.3.3 |
show Summary: Tornado's interpretation of symbols `-`, `+`, and `_` within chunk lengths and 'Content-Length' values contradicts the HTTP RFCs stipulations, potentially creating an avenue for request smuggling. This issue is generally found when Tornado operates behind specific proxies that understand these non-standard characters diversely, mostly observed in earlier versions of 'haproxy'; however, the latest version remains unaffected.
Details: Tornado utilizes the 'int' constructor to decipher the 'Content-Length' headers and chunk lengths in the locations mentioned below:
`tornado/http1connection.py:445`
Python3 code: self._expected_content_remaining = int(headers["Content-Length"])
`tornado/http1connection.py:621`
Python3 code: content_length = int(headers["Content-Length"])
`tornado/http1connection.py:671`
Python3 code: chunk_len = int(chunk_len_str.strip(), 16)
Notably, though the equation `int("0_0")` equates to `int("+0")`, `int("-0")`, and `int("0")`, using the 'int' constructor as a strategy for validating and parsing strings containing ASCII digits only is proven inadequate. |
| tornado | 6.0.3 | <6.5.0 |
show When Tornado's multipart/form-data parser encounters certain errors, it logs a warning but continues trying to parse the remainder of the data. This allows remote attackers to generate an extremely high volume of logs, constituting a DoS attack. This DoS is compounded by the fact that the logging subsystem is synchronous. |
| tornado | 6.0.3 | <6.4.2 |
show Tornado web framework affected versions contain a performance vulnerability in their HTTP cookie parser. When processing specially crafted malicious cookie headers, the parser's algorithm can exhibit quadratic time complexity. Since this parsing happens in the main event loop thread, it can cause the server to become unresponsive and block the processing of other incoming requests due to excessive CPU usage. |
| tornado | 6.0.3 | <6.3.2 |
show Tornado 6.3.2 includes a fix for CVE-2023-28370: Open redirect vulnerability in Tornado versions 6.3.1 and earlier allows a remote unauthenticated attacker to redirect a user to an arbitrary web site and conduct a phishing attack by having user access a specially crafted URL. |
| tornado | 6.0.3 | <6.4.1 |
show Tornado’s curl_httpclient.CurlAsyncHTTPClient class is vulnerable to CRLF (carriage return/line feed) injection in the request headers. |
| cryptography | 2.8 | <39.0.1 |
show Cryptography 39.0.1 updates its dependency 'OpenSSL' to v3.0.8 to include security fixes. https://github.com/pyca/cryptography/issues/8229 |
| cryptography | 2.8 | >=1.8,<39.0.1 |
show Cryptography 39.0.1 includes a fix for CVE-2023-23931: In affected versions 'Cipher.update_into' would accept Python objects which implement the buffer protocol, but provide only immutable buffers. This would allow immutable objects (such as 'bytes') to be mutated, thus violating fundamental rules of Python and resulting in corrupted output. This issue has been present since 'update_into' was originally introduced in cryptography 1.8. |
| cryptography | 2.8 | <3.3.2 |
show Cryptography 3.3.2 includes a fix for CVE-2020-36242: certain sequences of update calls to symmetrically encrypt multi-GB values could result in an integer overflow and buffer overflow, as demonstrated by the Fernet class. |
| cryptography | 2.8 | <42.0.8 |
show The `cryptography` library has updated its BoringSSL and OpenSSL dependencies in CI due to a security concern. Specifically, the issue involves the functions `EVP_PKEY_param_check()` and `EVP_PKEY_public_check()`, which are used to check DSA public keys or parameters. These functions can experience significant delays when processing excessively long DSA keys or parameters, potentially leading to a Denial of Service (DoS) if the input is from an untrusted source. The vulnerability arises because the key and parameter check functions do not limit the modulus size during checks, despite OpenSSL not allowing public keys with a modulus over 10,000 bits for signature verification. This issue affects applications that directly call these functions and the OpenSSL `pkey` and `pkeyparam` command-line applications with the `-check` option. The OpenSSL SSL/TLS implementation is not impacted, but the OpenSSL 3.0 and 3.1 FIPS providers are affected by this vulnerability. |
| cryptography | 2.8 | <42.0.0 |
show Cryptography starting from version 42.0.0 updates its CI configurations to use newer versions of BoringSSL or OpenSSL as a countermeasure to CVE-2023-5678. This vulnerability, affecting the package, could cause Denial of Service through specific DH key generation and verification functions when given overly long parameters. |
| cryptography | 2.8 | >=0.8,<41.0.3 |
show Cryptography 41.0.3 updates its bundled OpenSSL version to include a fix for a Denial of Service vulnerability. https://github.com/pyca/cryptography/commit/bfa4d95f0f356f2d535efd5c775e0fb3efe90ef2 https://www.openssl.org/news/secadv/20230719.txt |

show Cryptography 39.0.1 updates its dependency 'OpenSSL' to v3.0.8 to include security fixes. https://github.com/pyca/cryptography/issues/8229 |
| cryptography | 2.8 | <3.3 |
show Cryptography 3.3 no longer allows loading of finite field Diffie-Hellman parameters of less than 512 bits in length. This change is to conform with an upcoming OpenSSL release that no longer supports smaller sizes. These keys were already wildly insecure and should not have been used in any application outside of testing. https://github.com/pyca/cryptography/pull/5592 |
| cryptography | 2.8 | >=0.8,<41.0.3 |
show Cryptography 41.0.3 updates its bundled OpenSSL version to include a fix for a Denial of Service vulnerability. https://github.com/pyca/cryptography/commit/b22271cf3c3dd8dc8978f8f4b00b5c7060b6538d https://www.openssl.org/news/secadv/20230731.txt |
| cryptography | 2.8 | <42.0.5 |
show Cryptography version 42.0.5 introduces a limit on the number of name constraint checks during X.509 path validation to prevent denial of service attacks. https://github.com/pyca/cryptography/commit/4be53bf20cc90cbac01f5f94c5d1aecc5289ba1f |
| cryptography | 2.8 | <42.0.0 |
show Affected versions of Cryptography may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or sensitive data. |
| cryptography | 2.8 | <39.0.1 |
show Cryptography 39.0.1 updates its dependency 'OpenSSL' to v3.0.8 to include security fixes. https://github.com/pyca/cryptography/issues/8229 |

| cryptography | 2.8 | <41.0.2 |
show The cryptography package before 41.0.2 for Python mishandles SSH certificates that have critical options. |
| cryptography | 2.8 | <42.0.2 |
show The cryptography library has updated its OpenSSL dependency in CI due to security concerns. This vulnerability arises when processing maliciously formatted PKCS12 files, which can cause OpenSSL to crash, leading to a potential Denial of Service (DoS) attack. PKCS12 files, often containing certificates and keys, may come from untrusted sources. The PKCS12 specification allows certain fields to be NULL, but OpenSSL does not correctly handle these cases, resulting in a NULL pointer dereference and subsequent crash. Applications using OpenSSL APIs, such as PKCS12_parse(), PKCS12_unpack_p7data(), PKCS12_unpack_p7encdata(), PKCS12_unpack_authsafes(), and PKCS12_newpass(), are vulnerable if they process PKCS12 files from untrusted sources. Although a similar issue in SMIME_write_PKCS7() was fixed, it is not considered significant for security as it pertains to data writing. This issue does not affect the FIPS modules in versions 3.2, 3.1, and 3.0. |

tornado 6.0.3 has known security vulnerabilities.

This issue has been present since 'update_into' was originally introduced in cryptography 1.8. |
| cryptography | 2.8 | <3.3.2 |
show Cryptography 3.3.2 includes a fix for CVE-2020-36242: certain sequences of update calls to symmetrically encrypt multi-GB values could result in an integer overflow and buffer overflow, as demonstrated by the Fernet class. |
| cryptography | 2.8 | <42.0.8 |
show The `cryptography` library has updated its BoringSSL and OpenSSL dependencies in CI due to a security concern. Specifically, the issue involves the functions `EVP_PKEY_param_check()` and `EVP_PKEY_public_check()`, which are used to check DSA public keys or parameters. These functions can experience significant delays when processing excessively long DSA keys or parameters, potentially leading to a Denial of Service (DoS) if the input is from an untrusted source. The vulnerability arises because the key and parameter check functions do not limit the modulus size during checks, despite OpenSSL not allowing public keys with a modulus over 10,000 bits for signature verification. This issue affects applications that directly call these functions and the OpenSSL `pkey` and `pkeyparam` command-line applications with the `-check` option. The OpenSSL SSL/TLS implementation is not impacted, but the OpenSSL 3.0 and 3.1 FIPS providers are affected by this vulnerability. |
| cryptography | 2.8 | <42.0.0 |
show Cryptography starting from version 42.0.0 updates its CI configurations to use newer versions of BoringSSL or OpenSSL as a countermeasure to CVE-2023-5678. This vulnerability, affecting the package, could cause Denial of Service through specific DH key generation and verification functions when given overly long parameters. |

Update cryptography from 2.8 to 42.0.3
tornado 6.0.3 has known security vulnerabilities.
| Package | Installed | Affected | Info |
|---|---|---|---|
| tornado | 6.0.3 | <=6.4.0 |
show When Tornado receives a request with two Transfer-Encoding: chunked headers, it ignores them both. This enables request smuggling when Tornado is deployed behind a proxy server that emits such requests. Pound does this. |
| tornado | 6.0.3 | <6.3.3 |
show Summary: Tornado's interpretation of symbols `-`, `+`, and `_` within chunk lengths and 'Content-Length' values contradicts the HTTP RFCs stipulations, potentially creating an avenue for request smuggling. This issue is generally found when Tornado operates behind specific proxies that understand these non-standard characters diversely, mostly observed in earlier versions of 'haproxy'; however, the latest version remains unaffected.
Details: Tornado utilizes the 'int' constructor to decipher the 'Content-Length' headers and chunk lengths in the locations mentioned below:
`tornado/http1connection.py:445`
Python3 code: self._expected_content_remaining = int(headers["Content-Length"])
`tornado/http1connection.py:621`
Python3 code: content_length = int(headers["Content-Length"])
`tornado/http1connection.py:671`
Python3 code: chunk_len = int(chunk_len_str.strip(), 16)
Notably, though the equation `int("0_0")` equates to `int("+0")`, `int("-0")`, and `int("0")`, using the 'int' constructor as a strategy for validating and parsing strings containing ASCII digits only is proven inadequate. |
| tornado | 6.0.3 | <6.5.0 |
show When Tornado's multipart/form-data parser encounters certain errors, it logs a warning but continues trying to parse the remainder of the data. This allows remote attackers to generate an extremely high volume of logs, constituting a DoS attack. This DoS is compounded by the fact that the logging subsystem is synchronous. |
| tornado | 6.0.3 | <6.4.2 |
show Tornado web framework affected versions contain a performance vulnerability in their HTTP cookie parser. When processing specially crafted malicious cookie headers, the parser's algorithm can exhibit quadratic time complexity. Since this parsing happens in the main event loop thread, it can cause the server to become unresponsive and block the processing of other incoming requests due to excessive CPU usage. |
| tornado | 6.0.3 | <6.3.2 |
show Tornado 6.3.2 includes a fix for CVE-2023-28370: Open redirect vulnerability in Tornado versions 6.3.1 and earlier allows a remote unauthenticated attacker to redirect a user to an arbitrary web site and conduct a phishing attack by having user access a specially crafted URL. |
| tornado | 6.0.3 | <6.4.1 |
show Tornado’s curl_httpclient.CurlAsyncHTTPClient class is vulnerable to CRLF (carriage return/line feed) injection in the request headers. |

Python3 code: self._expected_content_remaining = int(headers["Content-Length"])
`tornado/http1connection.py:621`
Python3 code: content_length = int(headers["Content-Length"])
`tornado/http1connection.py:671`
Python3 code: chunk_len = int(chunk_len_str.strip(), 16)
Notably, though the equation `int("0_0")` equates to `int("+0")`, `int("-0")`, and `int("0")`, using the 'int' constructor as a strategy for validating and parsing strings containing ASCII digits only is proven inadequate. |
| tornado | 6.0.3 | <6.5.0 |
show When Tornado's multipart/form-data parser encounters certain errors, it logs a warning but continues trying to parse the remainder of the data. This allows remote attackers to generate an extremely high volume of logs, constituting a DoS attack. This DoS is compounded by the fact that the logging subsystem is synchronous. |
| tornado | 6.0.3 | <6.4.2 |
show Tornado web framework affected versions contain a performance vulnerability in their HTTP cookie parser. When processing specially crafted malicious cookie headers, the parser's algorithm can exhibit quadratic time complexity. Since this parsing happens in the main event loop thread, it can cause the server to become unresponsive and block the processing of other incoming requests due to excessive CPU usage. |
| tornado | 6.0.3 | <6.3.2 |
show Tornado 6.3.2 includes a fix for CVE-2023-28370: Open redirect vulnerability in Tornado versions 6.3.1 and earlier allows a remote unauthenticated attacker to redirect a user to an arbitrary web site and conduct a phishing attack by having user access a specially crafted URL. |
| tornado | 6.0.3 | <6.4.1 |
show Tornado’s curl_httpclient.CurlAsyncHTTPClient class is vulnerable to CRLF (carriage return/line feed) injection in the request headers. |

| cryptography | 2.8 | >=1.8,<39.0.1 |
show Cryptography 39.0.1 includes a fix for CVE-2023-23931: In affected versions 'Cipher.update_into' would accept Python objects which implement the buffer protocol, but provide only immutable buffers. This would allow immutable objects (such as 'bytes') to be mutated, thus violating fundamental rules of Python and resulting in corrupted output. This issue has been present since 'update_into' was originally introduced in cryptography 1.8. |
| cryptography | 2.8 | <3.3.2 |
show Cryptography 3.3.2 includes a fix for CVE-2020-36242: certain sequences of update calls to symmetrically encrypt multi-GB values could result in an integer overflow and buffer overflow, as demonstrated by the Fernet class. |
| cryptography | 2.8 | <42.0.8 |
show The `cryptography` library has updated its BoringSSL and OpenSSL dependencies in CI due to a security concern. Specifically, the issue involves the functions `EVP_PKEY_param_check()` and `EVP_PKEY_public_check()`, which are used to check DSA public keys or parameters. These functions can experience significant delays when processing excessively long DSA keys or parameters, potentially leading to a Denial of Service (DoS) if the input is from an untrusted source. The vulnerability arises because the key and parameter check functions do not limit the modulus size during checks, despite OpenSSL not allowing public keys with a modulus over 10,000 bits for signature verification. This issue affects applications that directly call these functions and the OpenSSL `pkey` and `pkeyparam` command-line applications with the `-check` option. The OpenSSL SSL/TLS implementation is not impacted, but the OpenSSL 3.0 and 3.1 FIPS providers are affected by this vulnerability. |
| cryptography | 2.8 | <42.0.0 |
show Cryptography starting from version 42.0.0 updates its CI configurations to use newer versions of BoringSSL or OpenSSL as a countermeasure to CVE-2023-5678. This vulnerability, affecting the package, could cause Denial of Service through specific DH key generation and verification functions when given overly long parameters. |

show The cryptography library has updated its OpenSSL dependency in CI due to security concerns. This vulnerability arises when processing maliciously formatted PKCS12 files, which can cause OpenSSL to crash, leading to a potential Denial of Service (DoS) attack. PKCS12 files, often containing certificates and keys, may come from untrusted sources. The PKCS12 specification allows certain fields to be NULL, but OpenSSL does not correctly handle these cases, resulting in a NULL pointer dereference and subsequent crash.

fix: requirements.txt to reduce vulnerabilities
The following vulnerabilities are fixed by pinning
tornado 6.0.3 has known security vulnerabilities.
| Package | Installed | Affected | Info |
|---|---|---|---|
| tornado | 6.0.3 | <=6.4.0 |
show When Tornado receives a request with two Transfer-Encoding: chunked headers, it ignores them both. This enables request smuggling when Tornado is deployed behind a proxy server that emits such requests. Pound does this. |
| tornado | 6.0.3 | <6.3.3 |
show Summary: Tornado's interpretation of symbols `-`, `+`, and `_` within chunk lengths and 'Content-Length' values contradicts the HTTP RFCs stipulations, potentially creating an avenue for request smuggling. This issue is generally found when Tornado operates behind specific proxies that understand these non-standard characters diversely, mostly observed in earlier versions of 'haproxy'; however, the latest version remains unaffected.
Details: Tornado utilizes the 'int' constructor to decipher the 'Content-Length' headers and chunk lengths in the locations mentioned below:
`tornado/http1connection.py:445`

Python3 code: content_length = int(headers["Content-Length"])
`tornado/http1connection.py:671`
Python3 code: chunk_len = int(chunk_len_str.strip(), 16)
Notably, though the equation `int("0_0")` equates to `int("+0")`, `int("-0")`, and `int("0")`, using the 'int' constructor as a strategy for validating and parsing strings containing ASCII digits only is proven inadequate. |
| tornado | 6.0.3 | <6.5.0 |

This allows remote attackers to generate an extremely high volume of logs, constituting a DoS attack. This DoS is compounded by the fact that the logging subsystem is synchronous. |

pyup-update-coverage-5.0.3-to-7.4.0
1 year, 8 months ago
Update coverage from 5.0.3 to 7.4.0
tornado 6.0.3 and cryptography 2.8 have known security vulnerabilities.
| Package | Installed | Affected | Info |
|---|---|---|---|
| tornado | 6.0.3 | <=6.4.0 |
show When Tornado receives a request with two Transfer-Encoding: chunked headers, it ignores them both. This enables request smuggling when Tornado is deployed behind a proxy server that emits such requests. Pound does this. |
| tornado | 6.0.3 | <6.3.3 |
show Summary: Tornado's interpretation of symbols `-`, `+`, and `_` within chunk lengths and 'Content-Length' values contradicts the HTTP RFCs stipulations, potentially creating an avenue for request smuggling. This issue is generally found when Tornado operates behind specific proxies that understand these non-standard characters diversely, mostly observed in earlier versions of 'haproxy'; however, the latest version remains unaffected.
Details: Tornado utilizes the 'int' constructor to decipher the 'Content-Length' headers and chunk lengths in the locations mentioned below:
`tornado/http1connection.py:445`
Python3 code: self._expected_content_remaining = int(headers["Content-Length"])
`tornado/http1connection.py:621`
Python3 code: content_length = int(headers["Content-Length"])
`tornado/http1connection.py:671`
Python3 code: chunk_len = int(chunk_len_str.strip(), 16)
Notably, though the equation `int("0_0")` equates to `int("+0")`, `int("-0")`, and `int("0")`, using the 'int' constructor as a strategy for validating and parsing strings containing ASCII digits only is proven inadequate. |
| tornado | 6.0.3 | <6.5.0 |
show When Tornado's multipart/form-data parser encounters certain errors, it logs a warning but continues trying to parse the remainder of the data. This allows remote attackers to generate an extremely high volume of logs, constituting a DoS attack. This DoS is compounded by the fact that the logging subsystem is synchronous. |
| tornado | 6.0.3 | <6.4.2 |
show Tornado web framework affected versions contain a performance vulnerability in their HTTP cookie parser. When processing specially crafted malicious cookie headers, the parser's algorithm can exhibit quadratic time complexity. Since this parsing happens in the main event loop thread, it can cause the server to become unresponsive and block the processing of other incoming requests due to excessive CPU usage. |
| tornado | 6.0.3 | <6.3.2 |
show Tornado 6.3.2 includes a fix for CVE-2023-28370: Open redirect vulnerability in Tornado versions 6.3.1 and earlier allows a remote unauthenticated attacker to redirect a user to an arbitrary web site and conduct a phishing attack by having user access a specially crafted URL. |
| tornado | 6.0.3 | <6.4.1 |
show Tornado’s curl_httpclient.CurlAsyncHTTPClient class is vulnerable to CRLF (carriage return/line feed) injection in the request headers. |
| cryptography | 2.8 | <39.0.1 |
show Cryptography 39.0.1 updates its dependency 'OpenSSL' to v3.0.8 to include security fixes. https://github.com/pyca/cryptography/issues/8229 |
| cryptography | 2.8 | >=1.8,<39.0.1 |
show Cryptography 39.0.1 includes a fix for CVE-2023-23931: In affected versions 'Cipher.update_into' would accept Python objects which implement the buffer protocol, but provide only immutable buffers. This would allow immutable objects (such as 'bytes') to be mutated, thus violating fundamental rules of Python and resulting in corrupted output. This issue has been present since 'update_into' was originally introduced in cryptography 1.8. |
| cryptography | 2.8 | <3.3.2 |
show Cryptography 3.3.2 includes a fix for CVE-2020-36242: certain sequences of update calls to symmetrically encrypt multi-GB values could result in an integer overflow and buffer overflow, as demonstrated by the Fernet class. |
| cryptography | 2.8 | <42.0.8 |
show The `cryptography` library has updated its BoringSSL and OpenSSL dependencies in CI due to a security concern. Specifically, the issue involves the functions `EVP_PKEY_param_check()` and `EVP_PKEY_public_check()`, which are used to check DSA public keys or parameters. These functions can experience significant delays when processing excessively long DSA keys or parameters, potentially leading to a Denial of Service (DoS) if the input is from an untrusted source. The vulnerability arises because the key and parameter check functions do not limit the modulus size during checks, despite OpenSSL not allowing public keys with a modulus over 10,000 bits for signature verification. This issue affects applications that directly call these functions and the OpenSSL `pkey` and `pkeyparam` command-line applications with the `-check` option. The OpenSSL SSL/TLS implementation is not impacted, but the OpenSSL 3.0 and 3.1 FIPS providers are affected by this vulnerability. |
| cryptography | 2.8 | <42.0.0 |
show Cryptography starting from version 42.0.0 updates its CI configurations to use newer versions of BoringSSL or OpenSSL as a countermeasure to CVE-2023-5678. This vulnerability, affecting the package, could cause Denial of Service through specific DH key generation and verification functions when given overly long parameters. |
| cryptography | 2.8 | >=0.8,<41.0.3 |
show Cryptography 41.0.3 updates its bundled OpenSSL version to include a fix for a Denial of Service vulnerability. https://github.com/pyca/cryptography/commit/bfa4d95f0f356f2d535efd5c775e0fb3efe90ef2 https://www.openssl.org/news/secadv/20230719.txt |

show Cryptography 39.0.1 updates its dependency 'OpenSSL' to v3.0.8 to include security fixes. https://github.com/pyca/cryptography/issues/8229 |
| cryptography | 2.8 | <3.3 |
show Cryptography 3.3 no longer allows loading of finite field Diffie-Hellman parameters of less than 512 bits in length. This change is to conform with an upcoming OpenSSL release that no longer supports smaller sizes. These keys were already wildly insecure and should not have been used in any application outside of testing. https://github.com/pyca/cryptography/pull/5592 |
| cryptography | 2.8 | >=0.8,<41.0.3 |
show Cryptography 41.0.3 updates its bundled OpenSSL version to include a fix for a Denial of Service vulnerability. https://github.com/pyca/cryptography/commit/b22271cf3c3dd8dc8978f8f4b00b5c7060b6538d https://www.openssl.org/news/secadv/20230731.txt |
| cryptography | 2.8 | <42.0.5 |
show Cryptography version 42.0.5 introduces a limit on the number of name constraint checks during X.509 path validation to prevent denial of service attacks. https://github.com/pyca/cryptography/commit/4be53bf20cc90cbac01f5f94c5d1aecc5289ba1f |
| cryptography | 2.8 | <42.0.0 |
show Affected versions of Cryptography may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or sensitive data. |
| cryptography | 2.8 | <39.0.1 |
show Cryptography 39.0.1 updates its dependency 'OpenSSL' to v3.0.8 to include security fixes. https://github.com/pyca/cryptography/issues/8229 |

| cryptography | 2.8 | <41.0.2 |
show The cryptography package before 41.0.2 for Python mishandles SSH certificates that have critical options. |
| cryptography | 2.8 | <42.0.2 |
show The cryptography library has updated its OpenSSL dependency in CI due to security concerns. This vulnerability arises when processing maliciously formatted PKCS12 files, which can cause OpenSSL to crash, leading to a potential Denial of Service (DoS) attack. PKCS12 files, often containing certificates and keys, may come from untrusted sources. The PKCS12 specification allows certain fields to be NULL, but OpenSSL does not correctly handle these cases, resulting in a NULL pointer dereference and subsequent crash. Applications using OpenSSL APIs, such as PKCS12_parse(), PKCS12_unpack_p7data(), PKCS12_unpack_p7encdata(), PKCS12_unpack_authsafes(), and PKCS12_newpass(), are vulnerable if they process PKCS12 files from untrusted sources. Although a similar issue in SMIME_write_PKCS7() was fixed, it is not considered significant for security as it pertains to data writing. This issue does not affect the FIPS modules in versions 3.2, 3.1, and 3.0. |
