Moderate: python-cryptography security, bug fix, and enhancement update
The python-cryptography packages contain a Python Cryptographic Authority's (PyCA's) cryptography library, which provides cryptographic primitives and recipes to Python developers.
The following packages have been upgraded to a later upstream version: python-cryptography (3.2.1). (BZ#1873581, BZ#1891947)
Security Fix(es):
-
python-cryptography: bleichenbacher timing oracle attack against RSA decryption (CVE-2020-25659)
-
python-cryptography: certain sequences of update() calls when symmetrically encrypting very large payloads could result in an integer overflow and lead to buffer overflows (CVE-2020-36242)
