<description>
<p>
Chris Evans has discovered various integer and stack overflows in libXpm,
which is shipped as a part of the X Window System. LessTif, an application
that includes this library, is susceptible to the same issues.
</p>
</description>
<impact type="normal">
<p>
A carefully-crafted XPM file could crash applications that are linked
against libXpm, such as LessTif, potentially allowing the execution of
arbitrary code with the privileges of the user running the application.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All LessTif users should upgrade to the latest version:
</p>
<code>
# emerge sync
# emerge -pv ">=x11-libs/lesstif-0.93.97"
# emerge ">=x11-libs/lesstif-0.93.97"</code>
</resolution>
