Summary
Moderate: python38:3.8 security, bug fix, and enhancement update
Details

Python is an interpreted, interactive, object-oriented programming language, which includes modules, classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to many system calls and libraries, as well as to various windowing systems.

The following packages have been upgraded to a later upstream version: python38 (3.8.3). (BZ#1847416)

Security Fix(es):

  • PyYAML: command execution through python/object/apply constructor in FullLoader (CVE-2019-20477)

  • python: infinite loop in the tarfile module via crafted TAR archive (CVE-2019-20907)

  • PyYAML: arbitrary command execution through python/object/new when FullLoader is used (CVE-2020-1747)

  • python: wrong backtracking in urllib.request.AbstractBasicAuthHandler allows for a ReDoS (CVE-2020-8492)

  • python: DoS via inefficiency in IPv{4,6}Interface classes (CVE-2020-14422)

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.
