How to fix?

Upgrade Ubuntu:14.04 python3.5 to version 3.5.2-2ubuntu016.04.414.04.1+esm1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python3.5 package and not the python3.5 package as distributed by Ubuntu. See How to fix? for Ubuntu:14.04 relevant fixed versions and status.

In Lib/tarfile.py in Python through 3.8.3, an attacker is able to craft a TAR archive leading to an infinite loop when opened by tarfile.open, because _proc_pax lacks header validation.
