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. (CVE-2019-20907)

Vulnerable Component: BIG-IP ASM, APM,LTM

Affected Versions:
16.0.0 - 16.0.1
15.1.0 - 15.1.3
14.1.0 - 14.1.4
13.1.0 - 13.1.4
12.1.0 - 12.1.6

QID Detection Logic(Authenticated):
This QID checks for the vulnerable versions of F5 BIG-IP devices using the tmsh command.

A user-created custom Python script utilizing the Python tarfile library may enter an infinite loop, consuming resources and causing a denial of service. The Python tarfile library is not used by any standard F5-supplied software.
