-------------------------------------------------------------------------
    HEWLETT-PACKARD COMPANY SECURITY BULLETIN: #00088, 30 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:  A SNMP community string in HP OpenView allow access to
          certain SNMP variables.

PLATFORM: HP 9000 series 700/800.

DAMAGE:   May reduce manageability of affected HP-UX systems.

SOLUTION: Install the patches listed below.

AVAILABILITY:  All patches are available now.

-------------------------------------------------------------------------
I.
   A. Background
      Reference: ISS X-force SNMP community resource notice,
                 dated November 2nd, 1998.

      A SNMP community string exists in HP OpenView SNMP agent
      implementations allowing access to certain SNMP variables.

      This may result in limited manageability of affected HP-UX
      systems.  The system remains operational but will be unable
      to respond to some queries from a management server.
      This problem is not an OpenView-specific problem, but OpenView
      can be affected when communicating with systems that have an
      affected agent.

      This HP OpenView Emanate SNMP Agent has two revisions currently
      supported, release 2.X and 14.X.  HP recommends upgrading to
      the 14.X release and applying the patch to circumvent this
      vulnerability.

   B. Fixing the problem
      The defect is now fixed such that an unauthorized user can not
      use this mechanism.  Please install the applicable patch:

        Emanate 14.2 version on HP-UX revision 11.00:        PHSS_16846
        Emanate 14.2 version on HP-UX revision 10.20:        PHSS_16845
        Emanate 14.0 version on HP-UX revision 10.0X, 10.10: PHSS_16800
        Emanate 14.0 version on HP-UX revision  9.X:         PHSS_16799

       Solaris 2.3 and 2.4    OpenView Emanate14.0 agent:    PSOV_02190
       Solaris 2.5.1 and 2.6  OpenView Emanate14.2 agent:    PSOV_02191

       The Solaris agent patches are available from:

   http://ovweb.external.hp.com:80/cpe/patches/emanate/14.x/sparc_2.X.html

 CAUTION: Installing any earlier HP OV Emanate patch, or reinstalling
          HP OpenView Network Node Manager (NNM) will reverse the
          protective effect of the patches listed above.  Reinstallation
          of the above referenced patch will then be necessary.
          This means that if a system administrator deinstalls one of
          the earlier patches after installing the security patch, they
          will overwrite the security fixes with older software.

          The Solaris, HP-UX 9.X, and HP-UX 10.X patches are _NOT_
          cumulative.  The HP-UX 11.X patch is, however, cumulative
          (one that supersedes), and will not be affected in this manner.
