Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-gfx/povray < 3.6.1-r4 >= 3.6.1-r4 Description =========== 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. Resolution ========== All POV-Ray users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/povray-3.6.1-r4" References ========== [ 1 ] CVE-2004-0768 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2004-0768 [ 2 ] CVE-2006-0481 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0481 [ 3 ] CVE-2006-3334 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3334 [ 4 ] CVE-2008-1382 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1382 [ 5 ] CVE-2008-3964 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-3964 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200812-15.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
