The latest MSIE-hole is now spreading.

THE ATTACHED HTML-code is served as a jpeg-file, and as MSIE ignores the
Content-Type if it "thinks" it knows better, then the code is executed.
This in combination with the malicious code that is possible to run, then
an "innocent.jpg" with the following content will log off an XP-user.
