  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

     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.

  ---------------------------------------------------------
  NNM  (Network Node Manager)
  ---------------------------------------------------------

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

**REVISED 03**
  ---------------------------------------------------------
--->> JetDirect Firmware
  ---------------------------------------------------------

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

   ----------------------------------------------------------
   HP-UX Systems running snmpd or OPENVIEW
   ----------------------------------------------------------
   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

  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.

--->> JetDirect Firmware
  ---------------------------------------------------------

  JetDirect Firmware Version      State
  ==========================      =====
--->>   X.08.32 and lower           VULNERABLE
--->>   (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.

--->>WORKAROUND: Change the set-community-name and use the
--->>Access Control List as described in "HP Jetdirect Print
--->>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
--->>that can be freely upgraded to X.08.32 or X.21.00 or
--->>higher firmware.  The latest firmware revision available
--->>for download is given.  For example, the latest firmware
--->>revision for the J3110A is G.08.32.

  The following patches are available now:

   PHSS_26137    s700_800  HP-UX 10.20 OV EMANATE14.2 Agent$
   PHSS_26138    s700_800  HP-UX 11.X  OV EMANATE14.2 Agent$
   PSOV_03087    Solaris 2.X      EMANATE Release 14.2 $

  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.
