How to fix?

Upgrade Centos:8 python2-docs to version 0:2.7.16-2.module+el8.1.0+3111+de3f2d8e or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python2-docs package and not the python2-docs package as distributed by Centos. See How to fix? for Centos:8 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.
