Security Vulnerabilities fixed in python-cryptography RHSA-2021:1608

Description

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) 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) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
