I.
   A. Background
      There are 2 problems with FTP Server (ftpd) on HP-UX.
      1. ftpd handling of the SITE EXEC command that allows remote
         users to gain root access.  This is possible in the default
         configuration of ftpd on HP-UX 11.0X ONLY.
      2. ftpd does not properly format the parameters to the
         setproctitle() function, allowing users to gain root access.
         This problem applies to both 11.0X and 10.XX.
