<p>
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.
</p>
</description>
<impact type="normal">
<p>
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.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All fbida users with the "fbcon" and "pdf" USE flags both enabled
should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-gfx/fbida-2.03-r4&quot;</code>
</resolution>
