Summary

Firefox before 1.0.5, Mozilla before 1.7.9, and Netscape 8.0.2 does not properly verify the associated types of DOM node names within the context of their namespaces, which allows remote attackers to modify certain tag properties, possibly leading to execution of arbitrary script or code, as demonstrated using an XHTML document with IMG tags with custom properties ("XHTML node spoofing").
