'Name' => 'Java AtomicReferenceArray Type Violation Vulnerability',
'Description' => %q{
This module exploits a vulnerability due to the fact that
AtomicReferenceArray uses the Unsafe class to store a reference in an
array directly, which may violate type safety if not used properly.
This allows a way to escape the JRE sandbox, and load additional classes
in order to perform malicious operations.
