PROBLEM:  The ftp server (ftpd) on HP-UX allows users root access.

PLATFORM:   HP-UX release 11.00 - Both Problem #1 and #2 below;
            HP-UX release 10.20 - Problem #2, setproctitle(), only

AVAILABILITY:  The temporary binary is available now.

CHANGE SUMMARY: Corrected typo in filename to be installed.
------------------------------------------------------------------------
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 11.00 ONLY.
      2. ftpd does not properly format the parameters to the
         setproctitle() function, allowing users to gain root access.
         This problem applies to both 11.00 and 10.X.

   B. Fixing the problem
      All system administrators are encouraged to install our temporary
      binary until an official patch is released.  The file can be
      retrieved to simply replace the original factory supplied binary.

   C. Recommended solution
      Two temporary ftpd binaries (for HP-UX 11.00 and HP-UX 10.20)
      can be found at:

       ftp://ftp.cup.hp.com/dist/networking/ftp/ftpd.11.0
       ftp://ftp.cup.hp.com/dist/networking/ftp/ftpd.10.20

**Revised 01**
--->>>These are to be installed in /usr/lbin/ftpd, with permissions 544.

      NOTE: This advisory will be updated when patches become available.
