Severity
  • 8.2 (High) CVSS_V3 - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H CVSS Calculator
Summary
Moderate: python-cryptography security, bug fix, and enhancement update
Details

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.
