This script is Copyright (C) 2005-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200502-32
(UnAce: Buffer overflow and directory traversal vulnerabilities)

Ulf Harnhammar discovered that UnAce suffers from buffer overflows
when testing, unpacking or listing specially crafted ACE archives
(CAN-2005-0160). He also found out that UnAce is vulnerable to
directory traversal attacks, if an archive contains './..' sequences or
absolute filenames (CAN-2005-0161).

Impact :

An attacker could exploit the buffer overflows to execute
malicious code or the directory traversals to overwrite arbitrary
files.

Workaround :

There is no known workaround at this time.

Solution :

All UnAce users should upgrade to the latest available 1.2
version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=app-arch/unace-1.2b-r1'

Risk factor :

Medium / CVSS Base Score : 5.1
