      HEWLETT-PACKARD SECURITY BULLETIN: #00009, 05 May 1994
---------------------------------------------------------------------------

_______________________________________________________________________
PROBLEM:  Incomplete implementation of OSF/AES standard
PLATFORM: HP 9000 Series 700 running HP-UX 9.01 or 9.03
DAMAGE:   Root may inadvertently grant improper ownership of files
          or directories.
SOLUTION: Disable OSF/AES implementation, reverting to original 8.07
          implementation by installing PHKL_4157 or PHKL_4161.
          Additional patch PHCO_3533 for cpio should be used as well.
_______________________________________________________________________


I. HP OSF/AES defect Update

   A. Fixing the problem

   The problem can be eliminated by applying a patch that corrects the
   HP OSF/AES defect. The patch reverts the behavior back to the 8.07
   implementation.

   Cpio had been patched to work around the problem.  This avoided
   the vulnerability at the cost of a minor and cosmetic loss of
   normal functionality.  Since PHKL_4157 or PHKL_4161 resolves the
   vulnerability, the cpio work around is no longer necessary.  The
   cpio patch PHCO_3533 removes the work around.


   B. How to Install the Patch

   1.  Get a copy of the patch from one of the following locations:

       a. HP SupportLine Mail Service

       To obtain the patch, send the following in the TEXT PORTION
       OF THE MESSAGE to support@support.mayfield.hp.com
       (no Subject is required):

                send PHKL_4157
                   -or-
                send PHKL_4161
                  -and, in another message-
                send PHCO_3533

       It will automatically be emailed back to you.  Note that
       users may also download the patch from HP SupportLine via
       ftp, kermit, or uucp.

       b. Response Center Support

       If you need additional assistance and have a support
       contract, you can contact your local Response Center for
       further help.

   2.  The patch information is current as of May 5, 1994.  You
       should list the patch:

             more PHKL_4157
                -or-
             more PHKL_4161
               -and-
             more PHCO_3533

       If it has been replaced there will be banner text saying:

                   OBSOLETE
                   REPLACED
                      BY
                   PHKL_NNNN


   3.  Apply the patch to your HP-UX system.  The complete instructions
       for applying the patch are in PHKL_NNNN.text.

   4.  Examine /tmp/update.log for any relevant WARNINGs or ERRORs.  This
       can be done as follows:

       a.  At the shell prompt, type "tail -60 /tmp/update.log | more"
       b.  Page through the next three screens via the space bar, looking
           for WARNING or ERROR messages.
