Hi, The following vulnerability was published for python-cryptography. CVE-2023-23931[0]: | 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. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
