  			'Description'=> %q{
  					This module exploits a stack-based buffer overflow on DVD X Player 5.5 Pro and
  				Standard.By supplying a long string of data in a plf file (playlist), the
  				MediaPlayerCtrl.dll component will attempt to extract a filename out of the string,
  				and then copy it on the stack without any proper bounds checking, which casues a
  				buffer overflow, and results arbitrary code execution under the context of the user.
  
  					This module has been designed to target common Windows systems such as:
  				Windows XP SP2/SP3, Windows Vista, and Windows 7.
