<p>
POV-Ray is a well known open-source ray tracer.

<description>
<p>
POV-Ray uses a statically linked copy of libpng to view and output PNG
files. The version shipped with POV-Ray is vulnerable to CVE-2008-3964,
CVE-2008-1382, CVE-2006-3334, CVE-2006-0481, CVE-2004-0768. A bug in
POV-Ray's build system caused it to load the old version when your
installed copy of libpng was >=media-libs/libpng-1.2.10.
</p>
</description>
<impact type="normal">
<p>
An attacker could entice a user to load a specially crafted PNG file as
a texture, resulting in the execution of arbitrary code with the
permissions of the user running the application.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All POV-Ray users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/povray-3.6.1-r4"</code>
</resolution>
