<h3>
This will exploit overflow and execute calc.exe on WinXP Pro SP2<br>
(fully patched) against VMWare 5.5.1 Initialize ActiveX member.<br>
</h3>
I have only found a bad solution to this bug. Due to the fact that<br>
my controlling assembler is a call dword ptr[reg] I need to point<br>
to a location I control, fine. However my payload is random pretty<br>
much every run. Therefor I fill half a HUGE buffer with the address<br>
(pointer) to my evil buffer, which them trampolines me to shellcode<br>
<br>
call ptr [reg]<br>
[reg] -> 0xtrampoline<br>
0xtrampoline -> shellcode<br>
