And BTW, contrary to what I thought first, it's not only a MSIE/Outlook thing like the JPG exploit was, but it's browser independent since WMF will be delegated to the windows service that is the cause for the troubles. I guess if it's remaned to JPG, at least Opera will ignore it, because it's using its own JPG viewer that won't process JPGs any further that are not valid images AFAIK.
