     AFFECTED VERSIONS

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

     HP-UX B.11.22
     =============
     Streams.STREAMS-64SLIB
     fix: install libxti.2-pa20_64-perf and libxti.so.1-em_64-perf
     Streams.STREAMS-MIN
     fix: install libxti.2-pa11-perf and libxti.so.1-em_32-perf

     HP-UX B.11.11
     =============
     Streams.STREAMS-MIN
     fix: PHNE_27703 or subsequent

 --> HP-UX B.11.04
     =============
     Streams.STREAMS-MIN
     fix: PHNE_29525 or subsequent

     HP-UX B.11.00
     =============
     Streams.STREAMS-MIN
     fix: PHNE_27702 or subsequent

     END AFFECTED VERSIONS


 B. Recommended solution

**REVISED 01**
    HP-UX B.11.00 - Install PHNE_27902 or subsequent
 -->HP-UX B.11.04 - Install PHNE_29525 or subsequent
    HP-UX B.11.11 - Install PHNE_27703 or subsequent

    HP-UX B.11.22 - Download and install the fixed library
                    files as follows:

    Note:  All the files mentioned for download below are
           available from the following ftp site:

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

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

        Note: There is an ftp defect in IE5 that may result in
               a browser hang.  To work around this:
        - Select Tools -> Internet Options -> Advanced
        - Un-check the option:
        - Un-check the option:
                  [ ] Enable folder view for FTP sites

       a. Download the files into a protected directory
          such as /etc.

       b. Unpack the files with gunzip(1)

       c. Verify the cksum or the md5 sum.

   cksum 1108544931 131072 libxti.2-pa11-perf
   cksum 2236090027 134536 libxti.2-pa20_64-perf
   cksum 2022859293 302736 libxti.so.1-em_32-perf
   cksum 2166608329 312560 libxti.so.1-em_64-perf

   MD5 (libxti.2-pa11-perf) = 1b329234c5597973af09370de9557608
   MD5 (libxti.2-pa20_64-perf) = 09398b7e9e3c5a0f8745d3cff9c630a5
   MD5 (libxti.so.1-em_32-perf) = 1daddf724a3a495f97608d74394c6fe5
   MD5 (libxti.so.1-em_64-perf) = ebf9457a91f8c83449fa7cfe69b247e1

     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

      d. Cd to the directory containing the new files.

      Then:

      DIR=/usr/lib/pa20_64
      cp libxti.2-pa20_64-perf $DIR
      chmod 555 $DIR/libxti.2-pa20_64-perf
      chown bin $DIR/libxti.2-pa20_64-perf
      chgrp bin $DIR/libxti.2-pa20_64-perf
      mv $DIR/libxti.2 $DIR/orig_libxti.2
      mv $DIRlibxti.2-pa20_64-perf $DIR/libxti.2

      DIR=/usr/lib
      cp libxti.2-pa11-perf $DIR
      chmod 555 $DIR/libxti.2-pa11-perf
      chown bin $DIR/libxti.2-pa11-perf
      chgrp bin $DIR/libxti.2-pa20_64-perf
      mv $DIR/libxti.2 $DIR/orig_libxti.2
      mv $DIR/libxti.2-pa11-perf $DIR/libxti.2

      DIR=/usr/lib/hpux64
      cp libxti.so.1-em_64-perf $DIR
      chmod 555 $DIR/libxti.so.1-em_64-perf
      chown bin $DIR/libxti.so.1-em_64-perf
      chgrp bin $DIR/libxti.so.1-em_64-perf
      mv $DIR/libxti.so.1 $DIR/orig_libxti.so.1
      mv $DIR/libxti.so.1-em_64-perf $DIR/libxti.so.1

      DIR=/usr/lib/hpux32
      cp libxti.so.1-em_32-perf $DIR
      chmod 555 $DIR/libxti.so.1-em_32-perf
      chown bin $DIR/libxti.so.1-em_32-perf
      chgrp bin $DIR/libxti.so.1-em_32-perf
      mv $DIR/libxti.so.1 $DIR/orig_libxti.so.1
      mv $DIR/libxti.so.1-em_32-perf $DIR/libxti.so.1

      It is not necessary to reboot the system.  However,
      currently executing programs will continue to use the
      original libraries until they are restarted.  Rebooting
      the system insures that all programs use the new libraries.

    To -gain access- to the Security Patch Matrix, select
    the link for "The Security Bulletins Archive".  (near the
    bottom of the page)  Once in the archive the third link is
    to the current Security Patch Matrix. Updated daily, this
    matrix categorizes security patches by platform/OS release,
    and by bulletin topic.  Security Patch Check completely
    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/
    displayProductInfo.pl?productNumber=B6834AA
