NVD Description

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