A vulnerability was found in python-cryptography. In affected versions, Cipher.update_into would accept Python objects which implement the buffer protocol but provide only immutable buffers. This issue allows immutable objects (such as bytes) to be mutated, thus violating the fundamental rules of Python, resulting in corrupted output.
