Background ========== libwmf is a library for converting WMF files. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/libwmf < 0.2.8.4-r3 >= 0.2.8.4-r3 Description =========== The embedded fork of the GD library introduced a "use-after-free" vulnerability in a modification which is specific to libwmf. Impact ====== A remote attacker could entice a user to open a specially crafted WMF file, 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 libwmf users should upgrade to the latest version which no longer builds the GD library: # emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/libwmf-0.2.8.4-r3" References ========== [ 1 ] CVE-2009-1364 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1364 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200907-01.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.
