THE PROBLEM

The Ussr Labs team has recently discovered a null memory problem in the PGP Certificate Server, 

The issue we found is if anyone connect to the PGP Certificate Server Command Port (used for manage Server operations) 
default (Port 4000) and the server is unable to resolve your IP address to a host name it will cause the process containg 
the services to crash.


SPECIAL NOTE: That we take no responsibility for this code it is for educational purposes only.


Example:
Denied all the ways to resolve you ip to hostname and connect to port 4000 in the server.
