How to fix?

Upgrade Oracle:8 python2-virtualenv to version 0:15.1.0-19.module+el8.3.0+7833+4aaf98ce or higher.
This issue was patched in ELSA-2020-4654.

NVD Description

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