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 SUPPORT: For further information, contact HP Services support channel.
