Description

The unarj utility has been reported to have a vulnerability related to traversal style attacks (/../) and uncompressing an archive. As reported, this would allow an attacker to overwrite any file the victim user has permission to write to. unarj (or tar or zip) allows full/absolute paths in archives and could be used in the same fashion, regardless of using traversal notation. This is a non-issue.
