Hi,



There is buffer overflow in rundll32.exe when it is passed big string as
routine name for a module. I've tested this on WindowsXP SP1. But other
version of windows might be vuln.



rundll32.exe advpack32.dll,<'A'x499>



advpack32.dll is just example. Any executable/dll will work. The
cmdline does get converted to UNICODE. And EIP ends up being 00410041.
