Echo: python3.13: security update to 3.13.5-2+e41

medium Tenable Self-Hosted Container Security Plugin ID 477706

Description

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

 - tarfile.tar_filter could be bypassed using crafted link entries, including symlinks with empty or
 directory-like names, to redirect later archive members outside the intended extraction directory. This
 allowed a malicious tar archive to cause tarfile.extractall() with filter="tar" to write files outside the
 destination directory, subject to the permissions of the extracting process. This is the
 tarfile.tar_filter counterpart of CVE-2026-7774, which covered tarfile.data_filter. (CVE-2026-114583)

Solution

Update the python3.13 library and its related packages to version 3.13.5-2+e41 or later.
