Microsoft Internet Explorer Full Remote Compromise w/o User Intervention

Through a joint effort between Micheal Evanchik and Paul (me) of Greyhats Security, a Full Remote Compromise of 
Microsoft's Internet Explorer has been developed for SP2 which requires no user interaction. This exploit is based on 
several previous vulnerabilities and can be used to write an executable to a user's harddrive and run it, requiring 
nothing from the user except visiting a webpage. Microsoft was able to reproduce the issue and has agreed that the 
severity is indeed critical. Because the vulnerabilities (3 total, each based on different technologies) have been 
known and unpatched for quite some time, we have decided to release the information on this exploit in hopes that in 
the future Microsoft will work faster towards patching vulnerabilities that we security researchers disclose to them. 
This exploit is definately not for script kiddies and uses several files being hosted on a server so I doubt a worm 
will be released that uses this flaw, at least not before a pa!
 tch is released. The most common use for this in the pcomming months will probably be spyware. However, you can avoid 
all consequences of this exploit by disabling hta files, disabled active scripting, or switching to a different browser 
altogether. My recommendation is switch to FireFox (http://firefox.com). I use it; it's just like Internet Explorer, 
but with added features like skinning, customization, and O! the security :-)
