				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.
