    HEWLETT-PACKARD COMPANY SECURITY BULLETIN: #00087, 16 November 1998
-------------------------------------------------------------------------

The information in the following Security Bulletin should be acted upon
as soon as possible.  Hewlett-Packard Company will not be liable for any
consequences to any customer resulting from customer's failure to fully
implement instructions in this Security Bulletin as soon as possible.

-------------------------------------------------------------------------
PROBLEM: The vacation program erroneously passes parameters to sendmail.

PLATFORM: HP 9000 series 700/800 running HP-UX releases 9.X, 10.X
          and 11.0.

DAMAGE:  Remote users could modify system files.

SOLUTION: Install the patches listed below.

AVAILABILITY:  All patches are available now.

-------------------------------------------------------------------------
I.
   A. Background
      The vacation program shipped with HP-UX in /usr/bin/vacation
      suffers from a fault in that it misunderstands it's inputs and
      invokes sendmail with the wrong parameters.  Both sendmail 5.65
      and 8.7.6 are vulnerable to this malady.  Also the vacation
      program ignores a TO: header when the "O" is upper case.

   B. Fixing the problem
      Install the applicable patch:

       HP-UX revision 11.X for HP9000 Series 7/800:       PHNE_16295

       HP-UX revision 10.20 for HP9000 Series 7/800:      PHNE_14042

       HP-UX revision 10.0X-10 for HP9000 Series 7/800:   PHNE_16726

       HP-UX revision 9.X  for HP9000 Series 7/800:       PHNE_16725
