N/A
VULNERABILITY SUMMARY:

LAN management products or other functions that use port zero when
accessing an Integrated Lights Out (iLO) in a ProLiant server will
cause iLO to become unresponsive creating a Denial of Service.
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 VERSIONS
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:
