GLSA-200608-22 : fbida: Arbitrary command execution

This script is Copyright (C) 2006-2014 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-200608-22
(fbida: Arbitrary command execution)

Toth Andras has discovered a typographic mistake in the 'fbgs' script,
shipped with fbida if the 'fbcon' and 'pdf' USE flags are both enabled.
This script runs 'gs' without the -dSAFER option, thus allowing a
PostScript file to execute, delete or create any kind of file on the
system.

Impact :

A remote attacker can entice a vulnerable user to view a malicious
PostScript or PDF file with fbgs, which may result with the execution
of arbitrary code.

Workaround :

There is no known workaround at this time.

Solution :

All fbida users with the 'fbcon' and 'pdf' USE flags both enabled
should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=media-gfx/fbida-2.03-r4'

Risk factor :

Medium / CVSS Base Score : 5.1
