How to fix?

Upgrade Centos:7 python3-libs to version 0:3.6.8-18.el7 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python3-libs package and not the python3-libs package as distributed by Centos. See How to fix? for Centos:7 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.
