<description>
<p>
The embedded fork of the GD library introduced a "use-after-free"
vulnerability in a modification which is specific to libwmf.
</p>
</description>
<impact type="normal">
<p>
A remote attacker could entice a user to open a specially crafted WMF
file, possibly resulting in the execution of arbitrary code with the
privileges of the user running the application, or a Denial of Service.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All libwmf users should upgrade to the latest version which no longer
builds the GD library:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-libs/libwmf-0.2.8.4-r3&quot;</code>
</resolution>
