QID 356791: Amazon Linux Security Advisory for python-cryptography : ALAS2023-2023-459

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. (
