'Name' => 'Java Applet AverageRangeStatisticImpl Remote Code Execution',
'Description' => %q{
This module abuses the AverageRangeStatisticImpl from a Java Applet to run
arbitrary Java code outside of the sandbox, a different exploit vector than the one
exploited in the wild in November of 2012. The vulnerability affects Java version
7u7 and earlier.
