Summary
python-cryptography security update
Details

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers.

Security Fix(es):

In the cryptography package before 3.3.2 for Python, certain sequences of update calls to symmetrically encrypt multi-GB values could result in an integer overflow and buffer overflow, as demonstrated by the Fernet class.(CVE-2020-36242)
