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.

The leaking test case has been fixed upstream, so backport the patch.

python3-cryptography and python3-cryptography-vectors are actually the
same project but are on Pypi as two separate modules.
The test suite validates that they're the same version and fails if they
are not:
FAIL: tests/test_utils.py::test_vector_version
def test_vector_version():
> assert cryptography.__version__ == cryptography_vectors.__version__
E AssertionError: assert '36.0.2' == '36.0.1'
Catch this slightly earlier by mandating that python3-cryptography-ptest
pulls in an identically versioned python3-cryptography-vectors.
