 -----------------------------------------------------------------
PROBLEM:    Potential security vulnerability in sendmail

IMPACT:     Potential Denial of Service (DoS).

PLATFORM:   MPE 7.0 and 7.5 running Sendmail 8.12.1 A.01.00, as
            well as earlier unsupported freeware versions of
            sendmail.

SOLUTION:   Download and install the appropriate sendmail patch
                MPE/iX 7.5  SMLHD04A,
                MPE/iX 7.0  SMLHD03A,
                MPE/iX 6.5 (and earlier)  See below.

MANUAL ACTIONS: Yes - Non-HP-UX only
                See below.

AVAILABILITY:   All patches are available now on itrc.hp.com
 -----------------------------------------------------------------
 A. Background
    A potential security vulnerability with sendmail/iX 8.12.1
    A.01.00 has been reported in MPE/iX.  This potential
    vulnerability may result a remote Denial of Service (DoS)
    only.

    NOTE:  This is similar but not identical to the vulnerability
           reported in CERT/CC CA-2003-07, as MPE/iX implements
           sendmail differently.

    CERT/CC is tracking this issue as VU#398025  This reference
    number corresponds to CVE candidate CAN-2002-1337.

    NOTE: This problem does not impact HP NonStop Servers, nor
          HP OpenVMS, nor HP Tru64 UNIX/Trucluster Server.

 B. Recommended solution
    Download and install the following fixes on the appropriate
    HP3000 systems:
                MPE/iX 7.5  SMLHD04A,
                MPE/iX 7.0  SMLHD03A,
                MPE/iX 6.5 (and earlier)
    NOTE:
    On releases before 6.5 where sendmail is not officially
    supported, the SENDMAIL NMPRG within SMLHD03A or SMLHD04A
    will work for unsupported freeware versions.

    Download and unpack SMLHD03A or SMLHD04A, then manually copy
    the new SENDMAIL NMPRG into the appropriate group in the
    SENDMAIL account.
