CVE-2012-2871
First published: Fri Aug 31 2012(Updated: )
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.
