Echo: python3.13: security update to 3.13.5-2+e36

medium Tenable Self-Hosted Container Security Plugin ID 459660

Description

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

 - The ftpcp() function in Lib/ftplib.py was not updated when CVE-2021-4189 was fixed. While makepasv() was
 patched to replace server-supplied PASV host addresses with the actual peer address (getpeername()[0]),
 ftpcp() still calls parse227() directly and passes the raw attacker-controllable IP address and port to
 target.sendport(). This patch is related to CVE-2021-4189. (CVE-2026-8328)

Solution

Update the python3.13 library and its related packages to version 3.13.5-2+e36 or later.
