Background ========== libwmf is a library for reading and converting vector images in Microsoft's native Windows Metafile Format (WMF). Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/libwmf < 0.2.8.4 >= 0.2.8.4 Description =========== infamous41md discovered that libwmf fails to do proper bounds checking on the MaxRecordSize variable in the WMF file header. This could lead to an head-based buffer overflow. Impact ====== By enticing a user to open a specially crafted WMF file, a remote attacker could cause a heap-based buffer overflow and execute arbitrary code with the permissions of the user running the application that uses libwmf. Workaround ========== There is no known workaround for this issue. Resolution ========== All libwmf users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/libwmf-0.2.8.4" References ========== [ 1 ] CVE-2006-3376 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3376 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200608-17.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.
