      o  Security Bulletin Digest Split
        ------------------------------

        The security bulletins digest has been split into multiple digests
        based on the operating system (HP-UX, MPE/iX, and HP Secure OS
        Software for Linux).  You will continue to receive all security
        bulletin digests unless you choose to update your subscriptions. 
       
        To update your subscriptions, use your browser to access the
        IT Resource Center on the World Wide Web at:

         http://www.itresourcecenter.hp.com/

        Under the Maintenance and Support Menu, click on the "more..." link.
        Then use the 'login' link at the left side of the screen to login
        using your IT Resource Center User ID and Password.

        Under the notifications section (near the bottom of the page), select
        Support Information Digests.

        To subscribe or unsubscribe to a specific security bulletin digest,
        select or unselect the checkbox beside it. Then click the
        "Update Subscriptions" button at the bottom of the page.

      o  IT Resource Center World Wide Web Service
        ---------------------------------------------------

        If you subscribed through the IT Resource Center and would
        like to be REMOVED from this mailing list, access the
        IT Resource Center on the World Wide Web at:

         http://www.itresourcecenter.hp.com/

        Login using your IT Resource Center User ID and Password.
        Then select Support Information Digests (located under
        Maintenance and Support).  You may then unsubscribe from the
        appropriate digest.

      A. Background
        CERT has issued an advisory:
        CERT Advisory CA-2002-03 Multiple Vulnerabilities in Many
        Implementations of the Simple Network Management Protocol
        (SNMPv1) containing information about the vulnerabilities.
       
        Hewlett-Packard Company will revise this bulletin as new
        information becomes available.

        ---------------------------------------------------------
        hp Procurve switches
        ---------------------------------------------------------

        We are still in the process of determining which other HP
        Procurve products are subject to these vulnerabilities.
        We have created fixes for products below which will resolve
        these issues.  See Section C below.

        Customers can download these patches in the form of software
        upgrades at:
                  http://www.hp.com/rnd/software/switches.htm

                       Product                      Fix revision number
           ----------------------------------       --------------------
           HP Procurve Switch 2524   (J4813A)        F.04.08 or greater

           HP Procurve Switch 4108GL-bundle (J4861A) G.04.05 or greater

        Not all HP Procurve products have completed testing, nor are
        they listed here, and may or may not have these vulnerabilities.
        This bulletin will again be updated as new information becomes
        available.

        ---------------------------------------------------------

        Some problems found in NNM product were related to trap
        handling.  Patches are available.  See Section C below.

         ----------------------------------------------------------
         Any HP-UX 10.X or 11.X system running snmpd or snmpdm is
         vulnerable.  To determine if your HP-UX system has snmpd
         or snmpdm installed:

           swlist -l file | grep snmpd

      B. Fixing the problem
        Install the appropriate patch or firmware revision or work
        around problem as detailed below.

         Problems found in the NNM product (related only to trap
         handling) are addressed in patches available at:

      http://support.openview.hp.com/cpe/patches/nnm/6.2/s700_800_11.X.jsp

        ---------------------------------------------------------
        MC/ServiceGuard
        ---------------------------------------------------------
        MC/ServiceGuard is not affected.  Testing has been completed
        and neither MC/ServiceGuard nor ServiceGuard OPS Edition are
        negatively impacted.

        The ServiceGuard Manager product does not use the cluster
        SNMP and remains unaffected.

        ---------------------------------------------------------
        Event Monitoring System  (EMS)
        ---------------------------------------------------------
        Testing of the MC/ServiceGuard or ServiceGuard OPS Edition
        application with package resources defined using EMS High
        Availability Monitors has been completed and shows no
        vulnerability to this issue.

      --->>   (where X = A through K)
      --->>   X.21.00 and higher          NOT vulnerable
      --->>   (where X = L through P)

      --->>FIX STATUS: HP is working on a firmware fix.

      --->>Servers - Making HP Jetdirect Print Servers Secure on
      --->>the Network":

      --->>  http://www.hp.com/cposupport/networking/support_doc/
      --->>  bpj05999.html#P88_10129

      --->>      LIMITING THE VULNERABILITY

      --->>SNMPv1 security relies on the set community name. It is
      --->>important that a set-community-name be configured on the
      --->>Jetdirect device and that it be kept secret.

      --->>Jetdirect Print Servers offer an Access Control List that
      --->>can be used to specify which hosts can make SNMP
      --->>configuration changes to Jetdirect Print Servers.

      --->>The steps above can help prevent exploitation of the
      --->>vulnerability.  To eliminate the vulnerability before a fix
      --->>is available SNMP can be disabled on the Jetdirect device.

      --->>      DISABLING SNMP ON A JETDIRECT PRINT SERVER

      --->>1. Update the firmware to the highest level as described in
      --->>    the Jetdirect Upgrade Instructions document:

      --->> http://www.hp.com/cposupport/networking/support_doc/bpj06917.html

      --->>NOTE:    Disabling SNMP may affect device discovery and port
      --->>         monitors that use SNMP to get status on the device.
      --->>         Use this feature with care.

      --->>2.  Telnet to the Jetdirect device (on the latest firmware)
      --->>     and type:
      --->>                   snmp-config: 0
      --->>                   quit

      --->>This will completely disable SNMP on the Jetdirect device.


      --->>HP always recommends upgrading Jetdirect firmware for the
      --->>latest bug fixes and security benefits.  The upgrade firmware
      --->>and download utility are available free of charge:

      --->>http://www.hp.com/cposupport/networking/support_doc/bpj06917.html

      --->>The following is a list of JetDirect Product Numbers

        All three patches are available from:

         http://support.openview.hp.com/cpe/patches/

         In addition PHSS_26137 and PHSS_26138 are now available
         from:
               http://itrc.hp.com

        ============================================================
        NOTE: The patches are labeled OV (Open View).  However, the
        patches are also applicable to systems that are _NOT_
        running Open View.
        ============================================================

        Workaround for HP-UX Systems:

        If a patch is not available for your platform or you cannot
        install an available patch, snmpd and snmpdm can be disabled
        by removing their entries from /etc/services and removing the
        execute permissions from /usr/sbin/snmpd and /usr/sbin/snmpdm.
