cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. In affected versions
Cipher.update_intowould accept Python objects which implement the buffer protocol, but provide only immutable buffers. This would allow immutable objects (such asbytes) 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 sinceupdate_intowas originally introduced in cryptography 1.8. - References
