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.

|
Than Ngo discovered that kfax contains a private copy of the TIFF
|
|
library and is therefore subject to several known vulnerabilities (see
|
|
References).
|
|
</p>

<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 ">=kde-base/kdegraphics-3.3.2"</code>
|
|
</resolution>
