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


NOTICE:   There are no restrictions for distribution of this
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
