Hi, I have uncovered a bug in IE: *Description* Microsoft Internet Explorer 6.0 (other versions not tested) is vulnerable to a DoS when specially crafted html is present on a page. The vulnerability is in the processing of the OBJECT tag where the data attribute points to the same page as object tag. This causes IE's stack to overflow. *Tested* OS: Windows 2000 Pro SP3 (fully up-to-date) OS: Windows XP Pro SP1 (fully up-to-date) IE: Internet Explorer 6.0.2800.1106 SP1 *Ramifications* When the specially crafted HTML is present in a page, Internet Explorer will forcefully terminate all open sessions. The client machine is otherwise unharmed. Further ramifications have not been investigated. *Proof of Concept* The following HTML code will cause the above version of Internet Explorer to forcefully terminate: <object id="test" data="#" width="100%" height="100%" type="text/x-scriptlet" VIEWASTEXT></object> -- Ryan Emerle, BSCS Lead Systems Developer Interactive Network Systems, Inc. http://www.ins-business.com _______________________________________________ Full-Disclosure - We believe in it.
