'Name' => 'Network Associates PGP KeyServer 7 LDAP Buffer Overflow',
'Description' => %q{
This module exploits a stack overflow in the LDAP service that is
part of the NAI PGP Enterprise product suite. This module was tested
against PGP KeyServer v7.0. Due to space restrictions, egghunter is
used to find our payload - therefore you may wish to adjust WfsDelay.
