<description>
<p>
Jan Braun has discovered that the "fbgs" script provided by fbida
insecurely creates temporary files in the "/var/tmp" directory.
</p>
</description>
<impact type="normal">
<p>
A local attacker could create links in the temporary file
directory, pointing to a valid file somewhere on the filesystem. When
an affected script is called, this could result in the file being
overwritten with the rights of the user running the script.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All fbida users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-gfx/fbida-2.03-r3&quot;</code>
</resolution>
