5  PROBLEMS ADDRESSED IN VAXDWMOTMUP01_073 KIT


      o  Compaq has  determined  that  systems  running  OpenVMS  Alpha,
         OpenVMS  VAX,  SEVMS  VAX  or  SEVMS  Alpha with the DECwindows
         MotifServer installed have a potential  security  vulnerability
         that  could  be  exploited to allow existing users unauthorized
         access to data and system resources.  To protect  against  this

         potential security risk, Compaq is making available a mandatory
         update patch for OpenVMS customers.

         Installation of the DECwindows Motif Server is optional  during
         the  installation  of  the  OpenVMS  Operating System.  You can
         verify whether or not the  DECwindows  Motif  Server  has  been
         installed on your system using the following command:

               $ DIRECTORY SYS$LIBRARY:DECW$*.EXE

         If  no  DECW$*.EXE  files  are  present  on  your  system,  the
         DECwindows Motif Server is not installed on your system and you
         do NOT need to apply this mandatory update.

         Apply this mandatory update if the DECwindow  Motif  Server  is
         installed  on  your  system  and  you  are  running  one of the
         following versions of OpenVMS or SEVMS:

          o  OpenVMS Alpha  Version  6.2  and  all  associated  hardware
             releases (for example, Version 6.2-1H1)

          o  OpenVMS Alpha Version 7.1-2

          o  OpenVMS Alpha Version 7.2-1

          o  OpenVMS Alpha Version 7.2-1H1

          o  OpenVMS Alpha Version 7.2-2

          o  OpenVMS Alpha Version 7.3

          o  OpenVMS VAX Version 6.2

          o  OpenVMS VAX Version 7.1

          o  OpenVMS VAX Version 7.2

          o  OpenVMS VAX Version 7.3

          o  SEVMS Alpha Version 6.2

          o  SEVMS VAX Version 6.2


                                      NOTE
                                      ----

         OpenVMS VAX V5.5-2 is not subject to  this  potential  security
         vulnerability.

         After completing the update, Compaq  strongly  recommends  that
         you perform an immediate backup of your system disk so that any
         subsequent restore  operations  begin  with  updated  software.
         Otherwise,  you  must reapply the update after a future restore
         operation.  Also, if at  some  future  time  you  upgrade  your
         system  to  one  of the versions of OpenVMS or SEVMS listed you

         must reapply the update.

         Images Affected:

          -  [SYSLIB]DECW$TRANSPORT_COMMON.EXE

          -  [SYSLIB]DECW$TRANSPORT_DECNET.EXE

          -  [SYSLIB]DECW$TRANSPORT_LOCAL.EXE

          -  [SYSLIB]DECW$TRANSPORT_TCPIP.EXE




6  KIT INSTALLATION RATING:

     The following kit  installation  rating,  based  upon  current  CLD
     information,  is  provided  to  serve as a guide to which customers
     should apply this remedial kit.  (Reference attached Disclaimer  of
     Warranty and Limitation of Liability Statement)

     INSTALLATION RATING:

       INSTALL_1 : To be installed by all customers.



7  INSTALLATION INSTRUCTIONS:

     Install this kit with the VMSINSTAL utility  by  logging  into  the
     SYSTEM account, and typing the following at the DCL prompt:

     @SYS$UPDATE:VMSINSTAL VAXDWMOTMUP01_073 [location of the saveset]


     The kit location may be a tape drive, CD, or a disk directory  that
     contains the kit.

     Note that the kit installation will ask if you wish to  delete  the
     old  files  rather  than  archive  them.   Due to the nature of the
     problem that this kit corrects,  Compaq  recommends  that  the  old
     files be deleted and not left on the system.

     This kit requires a system reboot.  Compaq strongly recommends that
     a  reboot  is performed immediately after kit installation to avoid
     system instability.

     If you have other nodes in your OpenVMS cluster, they must also  be
     rebooted  in  order  to make use of the new image(s).  If it is not
     possible or convenient to reboot the entire cluster at this time, a
     rolling  re-boot  may  be performed.  However, due to the nature of
     the problem that this kit corrects, Compaq  strongly  recommends  a
     rolling re-boot be performed immediately on each cluster node.
