Xbmc remote buffer overflow vulnerabilit

Code
`#!/usr/bin/env python   
'''  
Xbmc get tag from file name request remote buffer overflow 8.10 !!!   
  
Tested:Win xp sp2 eng  
Vendor url:http://xbmc.org/   
  
versions affected:   
Linux windows < tested   
other versions are also possibly affected.   
Release date:April the 1st 2009   
  
Restrictions:No filtering needed.  
This exploit happens when parsing and overly long id3  
tag to the web server.Dont think i covered this much  
in the poc code as i was running out of time on this  
exploit.  
  
  
We are able to overwrite the exception handlers also so   
creating a reliable exploit for vista and xps3 shouldn't   
be to hard have a look there are some modules loaded with   
out /safe seh.   
  
Credits to n00b for finding the buffer overflow and writing   
poc code and exploit.
