KDE is a feature-rich graphical desktop environment for Linux and
Unix-like Operating Systems. kfax (part of kdegraphics) is the KDE fax
file viewer.

<p>
Than Ngo discovered that kfax contains a private copy of the TIFF
library and is therefore subject to several known vulnerabilities (see
References).
</p>
</description>
<impact type="normal">
<p>
A remote attacker could entice a user to view a carefully-crafted TIFF
image file with kfax, which would potentially lead to execution of
arbitrary code with the rights of the user running kfax.
</p>
</impact>
<workaround>
<p>
The KDE Team recommends to remove the kfax binary as well as the
kfaxpart.la KPart:
</p>
<code>
rm /usr/kde/3.*/lib/kde3/kfaxpart.la
rm /usr/kde/3.*/bin/kfax</code>
<p>
Note: This will render the kfax functionality useless, if kfax
functionality is needed you should upgrade to the KDE 3.3.2 which is
not stable at the time of this writing.
</p>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All kfax users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=kde-base/kdegraphics-3.3.2&quot;</code>
</resolution>
