Internet Explorer XML and IMG Elements DoS
------------------------------------------------------------------------
SUMMARY
Internet Explorer vulnerable to a denial of service whenever it handles a
specially crafted XML or IMG element. Both of these are caused by null
pointer dereferences.
DETAILS
Vulnerable Systems:
* Microsoft Internet Explorer version 5
* Microsoft Internet Explorer version 6
Tested Combinations:
* Microsoft Windows XP Professional with Service Pack 2 and IE
6.0.2900.2180.xpsp_sp2_gdr.050301-1519
* Microsoft Windows Server 2003 with IE 6.0.2790.0
* Microsoft Windows 2000 Advanced Server 5.00.2195 with Service Pack 4
and IE 5.00.3700.1000
Microsoft(R) Internet Explorer 5 and Microsoft(R) Internet Explorer 6 are
vulnerable to a Denial of Service. So far all combinations of OS's and IE
versions I have tested are vulnerable. The exploit is triggered by bad
HTML data combined with a bad XML block, this HTML code can by hidden
inside a webpage etc.
Proof of Concept:
Any HTML page that contain the following HTML code will cause the DoS:
<table><tr><td><IMG align=left>X X X<?xml:namespace prefix=v ><v:X
style="HEIGHT:1"></td></tr></table>
