Affected versions of the cryptography package are vulnerable to Improper Input Validation due to missing prime-order subgroup validation for SECT elliptic-curve points. The public_key_from_numbers, EllipticCurvePublicNumbers.public_key(), load_der_public_key(), and load_pem_public_key() entry points accept attacker-supplied public keys without verifying that the provided point lies in the expected prime-order subgroup, enabling small-subgroup points to pass as valid.

Affected versions of the cryptography package are vulnerable to Improper Certificate Validation due to incomplete enforcement of DNS name constraints on peer names. The certificate validation logic applied DNS name constraints only to Subject Alternative Name (SAN) entries in child certificates, but did not apply the same checks to the peer name presented during validation, which allowed a mismatch between wildcard certificate matching and excluded subtree constraints.

Pyca/cryptography's wheels include a statically linked copy of OpenSSL. The versions of OpenSSL included in cryptography 42.0.0-44.0.0 are vulnerable to a security issue.

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.

Affected versions of the tornado package are vulnerable to Cookie Attribute Injection due to incomplete validation of values passed to the domain, path, and samesite arguments of the RequestHandler.set_cookie method. Specifically, semicolons are not rejected in these parameters, allowing crafted input to inject additional cookie attributes into the Set-Cookie header. An attacker who can influence cookie attribute values can override security-relevant attributes such as Secure, HttpOnly, or SameSite, potentially enabling session fixation or weakening cookie-based access controls.

Affected versions of the Tornado package are vulnerable to Denial of Service (DoS) due to uncontrolled multipart parsing complexity. The vulnerable multipart/form-data parser processes request bodies synchronously on the main thread, and before version 6.5.5 the only effective constraint on the number of multipart sections was max_body_size, which allows an attacker to submit a very large body containing an excessive number of parts and force expensive parsing work.

Affected versions of the tornado package are vulnerable to Improper Input Validation due to incomplete validation of cookie attribute values. The RequestHandler.set_cookie method does not completely validate the domain, path, and samesite arguments, allowing semicolons in these fields that can inject unintended cookie attributes into the resulting Set-Cookie header.
