NOTICE: There are no restrictions for distribution of this
Bulletin provided that it remains complete and intact.

The information in the following Security Bulletin should be
acted upon as soon as possible.  Hewlett-Packard Company will
not be liable for any consequences to any customer resulting
from customer's failure to fully implement instructions in this
Security Bulletin as soon as possible.

 -----------------------------------------------------------------
PROBLEM: Potential security vulnerability in B.11.11 DCE

IMPACT: Processes may fail.

PLATFORM: HP-UX B.11.11

SOLUTION: Manually install libcma files.

MANUAL ACTIONS: Yes - NonUpdate
 -->            HP-UX B.11.11 - Download and install libcma.1
 -->                            and libcma.2.

AVAILABILITY:  This bulletin will be revised when patches are
               available.

CHANGE SUMMARY: Rev.01 - libcma.1 and libcma.2 are available.
 -----------------------------------------------------------------
 A. Background

    PHNE_27063 introduced new behavior which can cause DCE
    libraries to fail.  The behavior is present in the
    superseding patches PHNE_28089 and PHNE_28895.

    The worm referred to as "Blaster" or "W32.Blaster.worm"
    creates network traffic which can lead to the DCE failure when
    PHNE_27063, PHNE_28089, or PHNE_28895 is installed.

    As the worm attempts to find new systems to infect it can
    cause programs to fail.  HP-UX is impacted as a side effect
    of the network traffic generated by the worm.

    The change introduced in PHNE_27063 may have a wide impact,
    but at this time the failure has been observed in programs
    which use libcma, such as /opt/dce/sbin/rpcd and the sd
    programs (swinstall, swlist, etc.).

    Note: The affected versions listed below may change when a
          fix is available.  If the fix is in a DCE library, that
          will be listed as the affected software.


     AFFECTED VERSIONS

     The following is a list by HP-UX revision of
     affected filesets or patches and fix information.
     To determine if a system has an affected version,
     search the output of "swlist -a revision -l fileset"
     for an affected fileset or patch, then determine if
     a fixed revision or applicable patch is installed.

**REVISED 01**
     HP-UX B.11.11
     =============
 --> DCE-Core.DCE-CORE-SHLIB
 --> fix: download and install libcma.1 and libcma.2.

     END AFFECTED VERSIONS


 B. Recommended solution

 -->Install PHSS_28386.  Then download libcma.1.1111.gz and
 -->and libcma.2.1111.gz from the following site:

        System:    hprc.external.hp.com  (192.170.19.51)
        Login:     libcma
        Password:  libcma

        FTP Access: ftp://libcma:libcma@hprc.external.hp.com/
                or: ftp://libcma:libcma@192.170.19.51/
                or: ftp hprc.external.hp.com


     Unpack libcma.1.1111.gz and libcma.2.1111.gz.  Verify
     the MD5 or cksum values.

     Note: If you wish to verify the md5 sum and you do not
           have a copy of md5, please refer to:
               HPSBUX9408-016
               Patch sums and the MD5 program
     Note: Using your itrc account security bulletins can be
          found here:
     http://itrc.hp.com/cki/bin/doc.pl/screen=ckiSecurityBulletin

     cksum:
        3576223673 532480 libcma.1.1111
         125364855 565248 libcma.2.1111

    MD5 (libcma.1.1111) = 6f540374dd00c1efc000f968835fed4c
    MD5 (libcma.2.1111) = e9bbb2135d466e941d43e1dbb22d6265


    Copy libcma.1.1111 and libcma.2.1111 into /usr/lib/.

        cd /usr/lib
        chown bin:bin libcma.1.1111
        chown bin:bin libcma.2.1111
        chmod 555 libcma.1.1111
        chmod 555 libcma.2.1111
        mv libcma.1 libcma.1.orig
        mv libcma.2 libcma.2.orig
        mv libcma.1.1111 libcma.1
        mv libcma.2.1111 libcma.2

    Restart all programs which use libcma.1 or libcma.2.
    The recommended way of restarting the those programs
    is to reboot the system.

    automates the process of reviewing the patch matrix for
    11.XX systems.  Please note that installing the patches
    listed in the Security Patch Matrix will completely
    implement a security bulletin _only_ if the MANUAL ACTIONS
    field specifies "No."

    The Security Patch Check tool can verify that a security
    bulletin has been implemented on HP-UX 11.XX systems providing
    that the fix is completely implemented in a patch with no
    manual actions required.  The Security Patch Check tool cannot
    verify fixes implemented via a product upgrade.

    For information on the Security Patch Check tool, see:
    http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/cgi/
