CVE-2023-23931 1 Cryptography Project 1 Cryptography 2023-02-16 N/A 6.5 MEDIUM
cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. 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 now correctly raises an exception. This issue has been present since `update_into` was originally introduced in cryptography 1.8.
CVE-2020-36242 3 Cryptography Project, Fedoraproject, Oracle 3 Cryptography, Fedora, Communications Cloud Native Core Network Function Cloud Native Environment 2022-12-06 6.4 MEDIUM 9.1 CRITICAL
In the cryptography package before 3.3.2 for Python, 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.
