python3.10 vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

Summary:

Python could be made to run programs if it received specially crafted
socket connections.

Software Description:

the multiprocessing module was being used. A local attacker could possibly
use this issue to execute arbitrary code and escalate privileges.
