NVD Description

Note: Versions mentioned in the description apply only to the upstream rpm package and not the rpm package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

A flaw was found in rpmuncompress. This command injection vulnerability allows a local attacker to execute arbitrary commands. This occurs when rpmuncompress processes a specially crafted archive filename containing shell metacharacters, which are not properly escaped before being passed to shell command strings. Successful exploitation requires user interaction, where a user or automated workflow invokes rpmuncompress on the malicious file, leading to high impact on the confidentiality, integrity, and availability of data accessible to the invoking user.
