Background ========== libxml2 is the XML (eXtended Markup Language) C parser and toolkit initially developed for the Gnome project. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/libxml2 < 2.9.4-r3 >= 2.9.4-r3 Description =========== Multiple vulnerabilities have been discovered in libxml2. Please review the CVE identifiers referenced below for details. Impact ====== A remote attacker, by enticing a user to process a specially crafted XML document, could remotely execute arbitrary code, conduct XML External Entity (XXE) attacks, or cause 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/libxml2-2.9.4-r3" Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
