					This module exploits a stack-based buffer overflow vulnerability in
				version <= 4.3.2.0 of Irfanview's JPEG2000.dll plugin. This exploit has been
				tested on a specific version of irfanview (v4.3.2), although other versions may
				work also. The vulnerability is triggered via parsing an invalid qcd chunk
				structure and specifying a malformed qcd size and data.

				Payload delivery and vulnerability trigger can be executed in multiple ways.
				The user can double click the file, use the file dialog, open via the icon
				and drag/drop the file into Irfanview\'s window. An egg hunter is used for
				stability.
