According to the Ruby style guide, %w{} collections for arrays of single
words are preferred. They're easier to type, and if you want a quick
grep, they're easier to search.
This change converts all Payloads to this format if there is more than
one payload to choose from.
It also alphabetizes the payloads, so the order can be more predictable,
and for long sets, easier to scan with eyeballs.

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.
