Background ========== OptiPNG is a PNG optimizer that recompresses image files to a smaller size, without losing any information. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-gfx/optipng < 0.6.2 >= 0.6.2 Description =========== A buffer overflow in the BMP reader in OptiPNG has been reported. Impact ====== A remote attacker could entice a user to process a specially crafted BMP image, possibly resulting in the execution of arbitrary code with the privileges of the user running the application, or a Denial of Service. Workaround ========== There is no known workaround at this time. Resolution ========== All OptiPNG users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/optipng-0.6.2" References ========== [ 1 ] CVE-2008-5101 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5101 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200812-01.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.
