"A buffer overflow bug has been discovered in unarj when handling long
file names contained in an archive. An attacker could create an
archive with a specially crafted path which could cause unarj to crash
or execute arbitrary instructions. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2004-0947
to this issue.

Additionally, a path traversal vulnerability exists in unarj which
allows an attacker to extract files to the parent ('..') directory.
When used recursively, this vulnerability can be used to overwrite
critical system files and programs.

Users of unarj are advised to upgrade to these packages.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
