          Critical Information about Potential Vulnerability in VMS

CIAC has learned of a potential vulnerability in VMS, OpenVMS and Security
Enhanced VMS (SEVMS) as described in the following advisory (which was
requested to be distributed intact) from Digital Equipment Corporation:
========================== Begin DEC Advisory =============================
  DATE:     23.FEB.1993
  SOURCE:   Digital Equipment Corporation
  AUTHOR:   Software Security Response Team
            Colorado Springs USA
  PRODUCT:  VMS V5.0 through OpenVMS V5.5-2 & OpenVMS AXP V1.0
  PROBLEM:  Potential Security Vulnerability - OpenVMS
  SOLUTION: A remedial kit is now available for OpenVMS AXP V1.0,
            VMS V5.0 through OpenVMS Version 5.5-2 (including all SEVMS
            versions V5.1 through V5.5-2 as applicable) by contacting
            your normal Digital Services Support organization.
  SEVERITY LEVEL: High

  This potential vulnerability has been corrected in the next release of
  OpenVMS, V6.0 and OpenVMS AXP, V1.5.  For VMS Versions prior to V5.0,
  Digital strongly recommends that you upgrade to a minimum of VMS V5.0
  and further, to the latest release of OpenVMS V5.5-2.
  _________________________________________________________________________
        The remedial kits may be identified as:
             VAXSYS01_U2050   VMS V5.0, V5.0-1, V5.0-2
             VAXSYS01_U1051   VMS V5.1 thru V5.1-1
             VAXSYS01_U1052   VMS V5.2, V5.2-1
             VAXSYS01_U2053   VMS V5.3 thru V5.3-2
             VAXSYS01_U3054   VMS V5.4 thru V5.4-3
             VAXSYS02_U2055   OpenVMS V5.5 thru V5.5-2
             AXPSYS01_010     OpenVMS AXP V1.0

  ADVISORY INFORMATION:
  _________________________________________________________________________
  This update kit corrects a potential security vulnerability in the VMS,
  OpenVMS VAX and OpenVMS AXP operating systems.  This potential
  vulnerability may be further exploited in the form of a malicious program
  that may allow authorized but unprivileged users to obtain all system
  privileges, potentially giving the unprivileged user control of your
  OpenVMS system and data.

  NOTE:
  The update kit must be applied if an update or installation is performed
  for all versions prior to OpenVMS V6.0 or OpenVMS AXP V1.5.  For VMS
  Versions prior to VMS V5.0, Digital strongly recommends that you upgrade
  to a minimum of VMS V5.0 and further to the latest release of OpenVMS
  V5.5-2.
  _________________________________________________________________________
  PATCH KIT INFORMATION:
  _________________________________________________________________________
  Digital strongly recommends that you install the available kit on your
  system(s), to avoid any potential vulnerability as a result of this
  problem.

  Customers with a Digital Services contract may obtain a kit for the
  affected versions of OpenVMS by contacting your normal support
  organizations.

  -  In the U.S. Customers may contact the Customer Support Center
     at 1(800)354-9000 and request the appropriate kit for your version
     of OpenVMS, or through DSNlink Text Search database using the
     keyword text "Potential Security Vulnerability", or DSNlink VTX using
     the patch number 1084

  -  Customers in other geographies should contact their normal Digital
     Services support organizations.

  As always, Digital recommends you to regularly review your system
  management and security procedures.  Digital will continue to review and
  enhance security features, and work with our customers to further improve
  the integrity of their systems.
