A denial of service flaw was found in the way libxml2 performed string
substitutions when entity values for entity references replacement was

when processed by an application linked against libxml2, would lead to
excessive CPU consumption. (CVE-2013-0338)
All users of libxml2 are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. The desktop must
be restarted (log out, then log back in) for this update to take effect.");
