'Description' => %q{
|
|
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.
