Remediation/Fixes

  1. If your product is deployed on WebSphere Application Server (WAS) and your deployment does not use an Eclipse based client nor the RM Browser plugin, then it is sufficient to continue using the existing version of your IBM Continuous Engineering product, and only upgrade the JRE in the WAS server.
  2. For the below remediations, if you have a WAS deployment, then WAS must also be remediated, in addition to performing your product upgrades. Follow instructions at Security Bulletin: Multiple Vulnerabilities in IBM® Java SDK affect WebSphere Application Server April 2020 CPU plus deferred CVE-2019-2949 and CVE-2020-2654 to get the WAS remediation.
  3. If you are deploying the IBM Engineering products to a WAS Liberty or a Tomcat Server, you will need to follow the instructions below to upgrade the JRE, and then must also configure to complete the upgrade process:


STEPS TO APPLY THE REMEDIATION:

1. Optionally, upgrade your products to an Extended Maintenance Release version: 6.0.6 or 6.0.6.1 Or optionally, upgrade to the latest 7.0 version.

2. Optionally, apply the latest iFix for your installed version.

3. Obtain the latest Java JRE CPU update for the IBM Java SDK using the following information.

4. Upgrade your JRE following the instructions in the link below:
How to update the IBM SDK for Java of IBM Engineering Lifecycle Management products based on version 6.0 or later of IBM's Jazz technology

5. Navigate to the server directory in your IBM Engineering product installation path, and go to jre/lib/security path.

6. Optionally, If you have not performed a Licenses upgrade as described in the link below, please follow the instructions to complete the setup:

No IBM Rational trial, server, or client access licenses available after upgrading Java and/or listed products
