- October 25, 1990
- VMS ANALYZE/PROCESS_DUMP
-
- -------------------------------------------------------------------------
-
- The CERT/CC has received a report of a security vulnerability which
- exists under specific conditions in Digital VMS Software (Versions 4.0
- to 5.4). The DESCRIPTION, IMPACT, SOLUTION, and CONTACT INFORMATION
- sections below have been provided to the CERT/CC by the Digital Equipment
- Corporation.
-
- -------------------------------------------------------------------------
- DESCRIPTION:
-
- Non-privileged users can acquire system privileges through
- the ANALYZE/PROCESS_DUMP routine.
-
-
- IMPACT:
-
- Non-privileged users who gain increased privileges might deliberately
- or inadvertently affect the integrity of system information and/or
- affect the integrity of the computing resource.
-
- SOLUTION:
-
- Digital is currently working on a permanent solution to this
- problem. While a permanent fix is being completed, Digital
- recommends that the following actions be taken on every VMS
- system (this includes all nodes in a VAXcluster system).
-
-
- After taking the following actions, non-privileged users will not be able
- to use the ANALYZE/PROCESS_DUMP command.
-
- 1. Log into the system account.
-
- 2. $ SET PROC/PRIV=ALL
-
- 3. a) For VMS versions prior to V5.0,
-
- Modify SYS$MANAGER:SYSTARTUP.COM to include the following lines:
-
- $ SET NOON
- $ MCR INSTALL ANALIMDMP.EXE/DELETE
-
- as the first two commands in this file.
-
- b) For VMS versions V5.0 and later,
-
- Modify SYS$MANAGER:SYSTARTUP_V5.COM to include the following
- lines:
-
- $ SET NOON
- $ MCR INSTALL ANALIMDMP.EXE/DELETE
-
- as the first two commands in this file.
-
- c) For MicroVMS systems,
-
- The image ANALIMDMP.EXE is not installed by default, but
- SYSTARTUP.COM contains a suggestion for installing the image if
- you have multiple users on your system. You must ensure that
- this image is not installed by SYSTARTUP.COM. You can use the
- following command to verify that the image is not installed:
-
- $ MCR INSTALL ANALIMDMP/LIST
-
- 4. $ MCR INSTALL ANALIMDMP/DELETE
-
- This command removes the installed image from the active system.
-
- 5. (Optional) Restart your systems and verify that the image is not
- installed using the following command:
-
- $ MCR INSTALL ANALIMDMP/LIST
-
- You should receive a message similar to the following:
-
- %INSTALL-W-FAIL, failed to LIST entry for ANALIMDMP.EXE
- -INSTALL-E-NOKFEFND, Known File Entry not found
-
