- -------------------------------------------------------------------------
      HEWLETT-PACKARD SECURITY BULLETIN: #HPSBUX9607-033, 18 July 1996
- -------------------------------------------------------------------------

Hewlett-Packard recommends that the information in the following
Security Bulletin 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
Bulletin as soon as possible.

- -------------------------------------------------------------------------
PROBLEM:  Vulnerability in /usr/lib/expreserve in HP-UX 9.X and 10.X
PLATFORM: HP 9000 series 300/400s and 700/800s
DAMAGE:   The default permissions of file expreserve(1) are in error,
          thereby allowing users to potentially gain root privileges
          on the host.
SOLUTION: Apply patch PHCO_6363 (series 700/800, HP-UX 9.x), or
                      PHCO_7833 (series 300/400, HP-UX 9.x), or
          perform the actions described below in releases of HP-UX prior
          to 9.X, and in 10.X)

AVAILABILITY: All patches are available now.

_________________________________________________________________________
I. Update


   A.  A private communication to HP described a vulnerability that
   allows ordinary users to potentially gain super-user privileges.
   The default permission for the file /usr/lib/expreserve (or on HP-UX
   10.X /usr/lbin/expreserve) needs only minimal prvileges.  If the
   patches mentioned above are applied the vulnerability cannot be
   exploited.

   In case no patches is available for your host HP-UX release, system
   administrators are asked to perform the following action to achieve
   the same result.


   B. Fixing the problem

   The vulnerability can be eliminated from releases 9.X of HP-UX
   by applying a patch.  Since some patches will not be made available
   on some releases of HP-UX (e.g., prior to 9.X, and now 10.0X),
   affected systems can be protected by system administrators.
   They should:

              $ su root
              # chmod 0555 /usr/lib/expreserve

   In the case of 10.X systems execute the following to affect the link
   target:

              $ su root
              # chmod 0555 /usr/lbin/expreserve

   Hewlett-Packard recommends that all customers concerned with the
   security of their HP-UX systems either apply the appropriate
   patch or perform the actions described above as soon as possible.


   C. How to Install the Patch (for HP-UX 9.x)

     1.  Determine which patch is appropriate for your hardware platform
         and operating system:

                      PHCO_6363 (series 700/800, HP-UX 9.x), or
                      PHCO_7833 (series 300/400, HP-UX 9.x)

     2.  Hewlett Packard's HP-UX patches are available via email
         and World Wide Web

         To obtain a copy of the HP SupportLine email service user's
         guide, send the following in the TEXT PORTION OF THE MESSAGE
         to support@us.external.hp.com (no Subject is required):

                               send guide

         The users guide explains the HP-UX patch downloading process
         via email and other services available.

         World Wide Web service for downloading of patches
         is available via our URL:
                  (http://us.external.hp.com)


     3.  Apply the patch to your HP-UX system.

     4.  Examine /tmp/update.log for any relevant WARNINGs or ERRORs.


    D. Impact

    The patch for HP-UX releases 9.X provides a proper permissions
    /usr/lib/expreserve which fixes the vulnerability.  No patches will
    be available for versions of HP-UX other than 9.X.  Instead, the
    workaround is described above.

         Bulletins from the HP SupportLine mail service via electronic
         mail, send an email message to:

Description: Security Vulnerability in rpc.pcnfsd & rpc.statd
===============================================================================

- -----------------------------------------------------------------------
HEWLETT-PACKARD SECURITY ADVISORY: #HPSBUX9607-032, 18 July 1996
- -----------------------------------------------------------------------

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:  Vulnerabilities in rpc.statd and rpc.pcnfsd executables.
PLATFORM: HP 9000/300 and 9000/400 systems running any currently
          supported version of HP-UX 9.X;  HP 9000/700 and 9000/800
          systems running any currently supported version of HP-UX
          9.X or any currently supported version of HP-UX 10.X.
DAMAGE:   The security of the enterprise and its applications could
          be compromised.

SOLUTION: Apply the following patches based on your system hardware
          and Operating System revision for the two problems:

                     PHNE_7371 (series 300/400 HP-UX 9.X) and
                     PHNE_7372 (series 300/400 HP-UX 9.X); or
                     PHNE_7072 (series 700/800 HP-UX 9.X), or
                     PHNE_7073 (series 700/800 HP-UX 10.X), or
                     PHNE_8015 (series 700 HP-UX 9.08 BLS), or
                     PHNE_8016 (series 700 HP-UX 9.09 BLS), or
                     PHNE_8017 (series 700 HP-UX 9.09+ BLS, or
                     PHNE_8018 (series 700 HP-UX 10.09 CMW), or
                     PHNE_8019 (series 700 HP-UX 10.09.01 CMW), or
                     PHNE_8020 (series 700 HP-UX 10.16 CMW).

AVAILABILITY:
          All of the above listed patches are available now via the
          mechanism described below, except for BLS/CMW system patches
          which will be available after 2 Sept.

- -----------------------------------------------------------------------
I.    Rpc.Pcnfsd - CERT(sm) Advisory CA-96.08

   A. Background

      The pcnfsd program (also called rpc.pcnfsd) is an authentication
      and printing program that runs on a UNIX server.  The rpc.pcnfsd
      binary that ships with HP systems contains a vulnerability that
      could allow a user to change permissions on a restricted file or
      directory.

   B. Fixing the problem

      Hewlett Packard is delivering a set of operating system dependent
      patches which contain a new version of rpc.pcnfsd.  Accompanying
      each patch is a README file which discusses the general purpose
      of the patch and describes how to apply it to your system.

   C. Recommended solution

      Apply one of the following patches based on your system hardware
      and operating system revision:

      s300/s400 9.X  - PHNE_7371 (rpc.pcnfsd)
      s700/s800 9.X  - PHNE_7072 (NFS Megapatch)
      s700/s800 10.X - PHNE_7073 (NFS Megapatch)

   D. Impact of the patch

      The patches described above provide a new version of the
      rpc.pcnfsd executable which fixes the vulnerability.



II.   Rpc.Pcnfsd - CERT(sm) Advisory CA-96.08

   A. Background

      The pcnfsd program (also called rpc.pcnfsd) is an authentication
      and printing program that runs on a UNIX server.  The rpc.pcnfsd
      binary that ships with most Unix systems contains a vulnerability
      that could allow users to execute arbitrary commands on the
      machine where pcnfsd runs.

   B. Fixing the problem

      The rpc.pcnfsd daemon that ships with Hewlett Packard systems
      does not make the system call that allows this vulnerability.
      Since HP systems are not vulnerable - there is no fix!



III.  Rpc.Statd - CERT(sm) Advisory CA-96.09

   A. Background

      The statd program (also called rpc.statd) is the status monitor
      program that helps keep track of remote file locks.  It works
      in conjunction with the lockd (also called rpc.lockd) daemon.
      The rpc.statd daemon that ships with HP systems contains a
      vulnerability that could allow a remote user to delete files
      on the system running rpc.statd.

   B. Fixing the problem

      Hewlett Packard is delivering a set of operating system dependent
      patches which contain a new version of rpc.statd.  Accompanying
      each patch is a README file which discusses the general purpose
      of the patch and describes how to apply it to your system.

   C. Recommended solution

      Apply one of the following patches based on your system hardware
      and operating system revision:

      s300/s400 9.X  - PHNE_7372 (rpc.statd)
      s700/s800 9.X  - PHNE_7072 (NFS Megapatch)
      s700/s800 10.X - PHNE_7073 (NFS Megapatch)

   D. Impact of the patch

      The patches described above provide a new version of the
      rpc.statd executable which fixes the vulnerability.
