I don't know the answer to your question, but I've asked the Microsoft
security folks for some way to turn off automatically opening WMF files in
IE. I made my query 3 or 4 WMF bugs ago, but got no reply.
Here's my new question: Can WMF images and auto-executing exploit code be
embedded in Word, Excel, and PowerPoint files?

There's exploit code out (http://www.milw0rm.com/exploits/5442) for MS08-021
describes GDI buffer overflows in the loading of EMF and WMF files.
There were other big problems in years past in the loading of these files.
Can anyone recall if the defaults for IE were changed with respect to
loading these files, perhaps from an IFRAME?
