Possible GDI Exploit Vector




Does anyone know if MSN Messenger 6 uses GDI+ to render jpeg images that appear 
as the profile images you see in MSN 6 Chat windows? If so, this could provide 
an extremely fast way to propagate a worm using the GDI+ flaw. All you would 
need to do to start it off is set the crafted image as ur profile picture, 
start conversations wtih people you know have MSN6 installed, and, if by 
default they display the other users' profile picture,they're machine would 
process the image and carry out any nasty deeds the image has within it (if the 
machine's not patched). 

For the worm to propagate, it would need to craft its code into the current 
users profile picture, and every time the infected user started a conversation 
with someone, it would spread as soon as the other user viewed the profile 
picture within the chat window.

The speed of spread would be enormous, granted that most people dont have up to 
date virus scanners/definitions and have not patched their machines. Plus it 
would be nearly impossible to determine where the virus came from, where it 
started off.

All this, of course, is only possible if MSN Messenger 6 does indeed use GDI+. 
Does it?
