Echo: python3.13: security update to 3.13.5-2+e37

high Tenable Cloud Security Plugin ID 465252

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - tarfile.extractall() with the 'data' or 'tar' filter could be bypassed by a crafted archive where a
 hardlink references a symlink stored at a deeper name than the hardlink itself. The extraction fallback
 validated the symlink at it's archived location but recreated it at the hardlink's shallower path, letting
 a relative target the filter judged contained escape the destination directory. This allowed a malicious
 tar archive to create a symlink pointing outside the destination, enabling out-of-destination file reads
 or writes. This was an incomplete fix of CVE-2025-4330. (CVE-2026-11940)

Solution

Update the python3.13 library and its related packages to version 3.13.5-2+e37 or later.
