| Microsoft Internet Explorer 6.0 DoS
Author : Ryan Emerle<firstname.lastname@example.org>
I have uncovered a bug in IE:
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.
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
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:
