      Title:  Recent sendmail patches for HP-UX releases 9.X thru 10.10

-------------------------------------------------------------------------
        HEWLETT-PACKARD SECURITY ADVISORY: #00054, 11 February 1997
-------------------------------------------------------------------------

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

-------------------------------------------------------------------------
PROBLEM:  Recent sendmail patches for HP-UX releases 9.X thru 10.10

PLATFORM: HP 9000 Series 700/800s running versions of HP-UX 9.X thru 10.10

DAMAGE:   Allows unauthorized access.

SOLUTION: Cleanse the password file as noted below on any machines which
          have ever had the following sendmail patches installed:

          PHNE_9621 on all platforms with HP-UX releases 9.X,
          PHNE_9622 on all platforms with HP-UX releases 10.00, 10.01,
                   and 10.10,
          PHNE_10033 on all platforms with HP-UX releases 9.X,

          NOTE HP-UX release 10.20 is not affected

AVAILABILITY: N/A
-------------------------------------------------------------------------
I.
   A. Background
      Since December 1996 three specific sendmail patches (PHNE_9621,
      PHNE_10033, and PHNE_9622) have been released by Hewlett-Packard
      Company. If installed, they incorrectly added new user and group
      entries in the password and group files.

      NOTE: HP-UX release 10.20 is not affected by this issue.


   B. Recommended solution
      The system administrator needs to perform the following commands
      on the command line only.  Do not use SAM to fix this issue at
      this time.

      grep '^sm[0-9]*' /etc/passwd

      The suspect entries have a ",.." in the password field.
      That ",.." entry needs to be replaced with a "*".  The change can
      be easily done with vipw (1M).

      Simply removing the patch will not remove these erroneous entries
      from the password file.  The action above needs to be taken
      whether or not the patch is removed.
