    SSRT4724 - HP integrated Lights Out (iLO) Denial of Service (DoS)
                     using port zero

    Bulletin provided that it remains complete and intact.
    The information in this Security bulletin should be acted
    upon as soon as possible.

    INITIAL RELEASE: 24 May 2004

    POTENTIAL SECURITY IMPACT: Denial of Service (DoS)

    SOURCE: HEWLETT-PACKARD COMPANY

    REFERENCES:N/A

    VULNERABILITY SUMMARY:

    Use Of TCP/IP Reserved Port Zero Causes Integrated Lights-Out
    (iLO) To Stop Responding. LAN management products that use
    port zero when accessing an Integrated Lights-Out (iLO) in a
    ProLiant server will cause iLO to become unresponsive. Port
    zero is specified as a reserved port by the Internet
    Engineering Task Force (IETF) and should not be used.

    SUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed.
    iLO Firmware V1.10 or Later up to, but not including, V1.55.

    BACKGROUND:
    This problem affects any LAN management product that uses port
    zero when accessing iLO in a ProLiant server. An updated
    listing of ProLiant servers with iLO is available at the following
    URL:
    http://h18013.www1.hp.com/products/servers/management/-
    riloe2/supported-servers.html

    AFFECTED VERSIONS

       iLO Firmware
       ------------
       action: install revision V1.55 or subsequent

    END AFFECTED VERSION

    RESOLUTION:
    Although HP recommends that port zero not be used (as it is
    specified as a reserved port by the Internet Engineering Task
    Force), if it is necessary to use port zero, upgrade the iLO
    firmware. iLO Firmware Version 1.55 allows the use of port
    zero without causing iLO to become unresponsive. iLO
    Firmware Version 1.55 is available at the following URL:
    http://h18004.www1.hp.com/support/files/lights-out/us/index.html
