NVD Description

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

A flaw was found in sos clean, a utility within the sos package. This vulnerability allows a local attacker to perform arbitrary file creation or overwrite. By crafting a malicious tar archive, an attacker can exploit a path traversal issue during tar extraction, where symlink and hardlink targets are not properly validated. This enables the attacker to write files to arbitrary locations on the system with the privileges of the sos clean process, which often runs as root.
