Background ========== gif2png is a command line program that converts image files from the Graphics Interchange Format (GIF) format to the Portable Network Graphics (PNG) format. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-gfx/gif2png < 2.5.1-r1 >= 2.5.1-r1 Description =========== gif2png contains a command line parsing vulnerability that may result in a stack overflow due to an unexpectedly long input filename. Impact ====== A remote attacker could entice a user to open a specially crafted image, possibly resulting in the execution of arbitrary code with the privileges of the user running the application, or a Denial of Service. Note that applications relying on gif2png to process images can also trigger the vulnerability. Workaround ========== There is no known workaround at this time. Resolution ========== All gif2png users should upgrade to the latest stable version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/gif2png-2.5.1-r1" References ========== [ 1 ] CVE-2009-5018 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-5018 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201101-01.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.
