					This module abuses the Color Management classes from a Java Applet to run
				arbitrary Java code outside of the sandbox as exploited in the wild in February
				and March of 2013. The vulnerability affects Java version 7u15 and earlier and 6u41
				and earlier and has been tested successfully on Windows XP SP3 and Windows 7 SP1
				systems. This exploit doesn't bypass click-to-play, so the user must accept the java
				warning in order to run the malicious applet.
