/*************************************************
Exploit for Microsoft Windows Messenger Heap Overflow (MS03-043)
based on PoC DoS by recca@mail.ru
by Adik < netmaniac [at] hotmail.kg >
http://netninja.to.kg
Binds command shell on port 9191
Tested on
Windows XP Professional SP1 English version
Windows 2000 Professional SP3 English version
access violation -> unhandledexceptionfilter ->
-> call [esi+48h]/call [edi+6ch] (win2kSP3/WinXPSP1) -> longjmp -> shellcode
attach debugger and c how it flows :) worked fine for me

hmm I'll test this out on some machines here if I can find some free time somewhere...  Thanks for the code, and the compilation m8!!! RB Just tested this on 5 boxes on the local network (2 Win2K3 SP3 and 3 WinX PRO with SP1) and it doesn't work.... :/ Still great work mate!!!!!
