NVD Description
Note: Versions mentioned in the description apply only to the upstream python3 package and not the python3 package as distributed by RHEL.
See How to fix? for RHEL:9 relevant fixed versions and status.
Allows the extraction filter to be ignored, allowing symlink targets to point outside the destination directory, and the modification of some file metadata.
You are affected by this vulnerability if using the tarfile module to extract untrusted tar archives using TarFile.extractall() or TarFile.extract() using the filter= parameter with a value of "data" or "tar". See the tarfile extraction filters documentation https://docs.python.org/3/library/tarfile.html#tarfile-extraction-filter for more information.
Note that for Python 3.14 or later the default value of filter= changed from "no filtering" to `"data", so if you are relying on this new default behavior then your usage is also affected.
Note that none of these vulnerabilities significantly affect the installation of source distributions which are tar archives as source distributions already allow arbitrary code execution during the build process. However when evaluating source distributions it's important to avoid installing source distributions with suspicious links.
Remediation
Upgrade RHEL:9 python3 to version 0:3.9.21-2.el9_6.1 or higher.
This issue was patched in RHSA-2025:10136.
