Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200812-15
(POV-Ray: User-assisted execution of arbitrary code)

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 :

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.

Workaround :

There is no known workaround at this time.
