     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.

    PSOV_03087 and PSOV_03113 are available from:

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

    PHSS_26367 and PHSS_26368 available from:
           http://itrc.hp.com

    PHSS_26510, PHSS_26137, and PHSS_26138 are available
    from both sites.

    The HP OC SS7 (OpenCall) products J3362A and J5938A running
    on HP-UX releases 10.20 and 11.X are not vulnerable if the
    applicable HP-UX patch listed above is installed.

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

    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.
