NVD Description

Note: Versions mentioned in the description apply only to the upstream python2.7 package and not the python2.7 package as distributed by Debian. See How to fix? for Debian:11 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.
