    SSRT4718 rev.0 HP Tru64 UNIX NTP Integer Overflow

     -----------------------------------------------------------------
    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: 02 July 2004

    POTENTIAL SECURITY IMPACT: Integer overflow on NTP server that
                                  corrupts the NTP Client time/date.

    SOURCE: HEWLETT-PACKARD COMPANY
                    HP Software Security Response Team

    REFERENCES: CERT VU#584606

    VULNERABILITY SUMMARY:

    The NTP (Network Time Protocol) package provided with
    HP Tru64 UNIX contains an integer overflow. The overflow
    may cause clients with clocks set too far in the past to
    receive an incorrect date/time offset from the ntp server,
    resulting in an incorrect date/time on the client.

    SUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed.

    HP Tru64 UNIX V5.1B (PK4)
    HP Tru64 UNIX V5.1B (PK3)
    HP Tru64 UNIX V5.1B (PK2)
    HP Tru64 UNIX V51.A (PK6)
    HP Tru64 UNIX V4.0G (PK4)
    HP Tru64 UNIX V4.0F (PK8)

    BACKGROUND:

    RESOLUTION:

    Until the corrections are available in mainstream release
    patch kits, HP is releasing the following Early Release Patch
    (ERP) kits.

    The ERP kits use dupatch to install and will not install over
    any installed Customer Specific Patches (CSPs) that have
    file intersections with the ERPs. Contact your service provider
    for assistance if the installation of the ERPs is blocked by any
    of your installed CSPs.

    The fixes contained in the ERP kits are scheduled to be available
    in the following mainstream patch kits:

    5.1B (PK5)
    5.1A (PK7)

    ERP kits are available for the versions listed below. The kits
    provide NTP V4.1.1 and distribute the following files:

    /usr/bin/ntpq
    /usr/bin/ntp
    /usr/bin/xntpdc
    /usr/sbin/ntpdate
    /usr/sbin/ntptrace
    /usr/sbin/xntpd
