libxml2 is the XML (eXtended Markup Language) C parser and toolkit initially developed for the Gnome project.
Multiple vulnerabilities have been discovered in libxml2. Please review the CVE identifiers referenced below for details.
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.
There is no known workaround at this time.
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.
