Synopsis
========
The fbgs script provided by fbida allows the execution of arbitrary
code.
Background
==========
fbida is a collection of image viewers and editors for the framebuffer
console and X11. fbgs is a PostScript and PDF viewer for the linux
framebuffer console.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/fbida < 2.03-r4 >= 2.03-r4
Description
===========
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.
Resolution
==========
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"
