libxml2: fix CVE-2014-3660

Browse Source 
It was discovered that the patch for CVE-2014-0191 for libxml2 is
incomplete.  It is still possible to have libxml2 incorrectly perform
entity substituton even when the application using libxml2 explicitly
disables the feature.  This can allow a remote denial-of-service attack on
systems with libxml2 prior to 2.9.2.
