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

 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

    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.

     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.

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

**Revised 01**
- -->> 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.
