Note: Versions mentioned in the description apply only to the upstream tar-rmt package and not the tar-rmt package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

This bypasses pre-extraction inspection mechanisms, potentially allowing an attacker to introduce malicious files onto a system without detection.
