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.</p> <p><strong>Affected:</strong> Ubuntu:Pro:18.04:LTS: python-cryptography, Ubuntu:20.04:LTS: python-cryptography, Ubuntu:22.04:LTS: python-cryptography</p> <p>cryptography is a package designed to expose cryptographic primitives and recipes to Python developers.
