From my experience on XP/2003, IE will only render WMF files as images if the "placeable" header has been added before the WMF header. The addition of the "placeable" header prevents the SetAbortProc from being reached in the Escape() function, due to a check on the device context (credits to mr. anonymous for that gem, I spent an hour beating my head on it).
I will try to publish an "exploit faq" later tonight, seems to be way too much confusion about this flaw... -HD On Wednesday 04 January 2006 17:27, Crist J.
