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.
