+libxml2 CVE-2012-2871
+
+the patch come from:
+http://src.chromium.org/viewvc/chrome/trunk/src/third_party/libxml/src \
+/include/libxml/tree.h?r1=56276&r2=149930
+
+libxml2 2.9.0-rc1 and earlier, as used in Google Chrome before 21.0.1180.89,
+does not properly support a cast of an unspecified variable during handling
+of XSL transforms, which allows remote attackers to cause a denial of service
+or possibly have unknown other impact via a crafted document, related to the
+_xmlNs data structure in include/libxml/tree.h.
