SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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.
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.
There is no known workaround at this time.
SolutionAll POV-Ray users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-gfx/povray-3.6.1-r4'
