Network Associates PGP Certificate Server Unresolveable IP Address DoS Vulnerability

PGP Certificate Server by default listens on port 4000 to allow remote server management and on port 5000 for PGP replication. If the server is unable to resolve the IP address of a machine connecting to either port to a hostname the service may crash with an error message warning that memory at address 0x00000000 could not be read.
