Background ========== libxml2 is the XML C parser and toolkit developed for the Gnome project. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/libxml2 < 2.9.2 >= 2.9.2 Description =========== parser.c in libxml2 before 2.9.2 does not properly prevent entity expansion even when entity substitution has been disabled. Impact ====== A context-dependent attacker could entice a user to a specially crafted XML file using an application linked against libxml2, possibly resulting in a Denial of Service condition. Workaround ========== There is no known workaround at this time. Resolution ========== All libxml2 users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/libxml2-2.9.2" Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying these packages. References ========== [ 1 ] CVE-2014-3660 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-3660 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201412-06.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.
