Please see "Workarounds and Mitigations"
Workarounds and Mitigations
Use the following instructions to download the latest JRE version from the IBM Java download portal and replace it with the JRE you are currently invoking.
Steps to update Java - QMF for Workstation:
- Download JRE 8.0.8.25 version from IBM Java download portal.
- Close QMF for workstation , if any instance is running.
- Copy 8.0.8.25 JRE version to C:\Program Files\IBM\Db2 Query Management Facility\QMF for Workstation\jre.
- Start application
Observations:
- While updating java in QMF for workstation for z/OS and Multiplatform build versions from 12.2.0.1 to 12.2.0.4 will reflect some issue for scheduled tasks after java update. Please update to QMF 12.2.0.5 before applying the java update for scheduled tasks to run without any issues.
- After migrating to QMF 12.2.0.5, update the java using above steps. To run Visual Reports, please set below 3 VM arguments in C:\Program Files\IBM\Db2 Query Management Facility\QMF for Workstation\eclipse.ini (QMF install directory)
-Djdk.xml.xpathExprGrpLimit=0
-Djdk.xml.xpathExprOpLimit=0
-Djdk.xml.xpathTotalOpLimit=0
Steps to update Java - QMF Vision:
1. Go to: https://adoptopenjdk.net/releases.html
2. Download Open JDK 8(LTS) and extract the files to a temporary location.
3. Stop the following Windows services:
- IBM QMF Vision Indexing Service (this will also stop IBM QMF Vision Web Service due to dependencies)
- QMFServerLite
4. Delete C:\Program Files\IBM\DB2 Query Management Facility\QMF Vision\elasticsearch\java\jre 1.8.0_362. (QMF Vision install directory)
Note: The folder name would be “jre” in case security bulletin reference # 0880785 is already applied.
5. Copy folder jre 1.8.0_412 from the temporary location to C:\Program Files\IBM\DB2 Query Management Facility\QMF Vision\elasticsearch\java. (QMF Vision install directory)
6. Rename folder jre 1.8.0_412 to jre.
Note: If the folder in the java folder is already renamed to “jre” via the security bulletin reference # 0880785, then steps 7 through 12 are not required. You can directly go to step 13 and start the relevant services,
Security bulletin # 0880785 link - https://www-01.ibm.com/support/docview.wss?uid=ibm10880785
7. Under C:\Program Files\IBM\DB2 Query Management Facility\QMF Vision\, edit the following 6 files:
elasticsearch/bin/install.bat
elasticsearch/bin/start.bat
elasticsearch/bin/stop.bat
elasticsearch/bin/uninstall.bat
qmfserver/bat/setenv.bat
qmfserver/conf/wrapper.conf
For each file, replace "jre1.8.0_362" with "jre", and save.
8. Open a Windows Command window in Administrator mode and Change directory to elasticsearch/bin.
9. Execute:
uninstall.bat
install.bat
10. Change directory to qmfserver/bat.
11. Execute:
uninstallService.bat
installService.bat.
12. In the Windows Services console, edit "IBM QMF Vision Indexing Service" to change startup type from "Manual" to "Automatic".
13. Restart Windows Services:
- IBM QMF Vision Indexing Service
- IBM QMF Vision Web Service
- QMFServerLite.

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
