Title:RHSA-2021:1608: python-cryptography security, bug fix, and enhancement update (Moderate)
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)

    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.
