|
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.

|
<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>
