   'Description'    => %q{
   This module exploits a buffer overflow vulnerability in adm_build_path()
  function of sadmind daemon.
  The distributed system administration daemon (sadmind) is the daemon used by 
  Solstice AdminSuite applications to perform distributed system administration 
  operations.
  The sadmind daemon is started automatically by the inetd daemon whenever a 
  request to invoke an operation is received. The sadmind daemon process 
  continues to run for 15 minutes after the last request is completed, unless a 
  different idle-time is specified with the -i command line option. The sadmind 
  daemon may be started independently from the command line, for example, at 
  system boot time. In this case, the -i option has no effect; sadmind continues 
  to run, even if there are no active requests.
