Remediation/Fixes
IMPORTANT CONSIDERATIONS:
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
Rational 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(R) Java
SDK affects WebSphere Application Server July 2018 CPU to get the WAS
remediation.
3. If you are deploying the Rational 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:
o Stop the server: Navigate to the Server directory in your Ratonal product
installation path and run this script: server.shutdown
o Navigate to the server directory in your Rational product installation
path, open server.startup script using prefered text editor (e.g., Notepad
for Windows or Vim Editor for Linux) and add one more option to the
healthcenter parameter set:
? Search parameter -Dcom.ibm.java.diagnostics.healthcenter.agent in
server.startup script to find the line containing the health center
parameter.
NOTE: For some Rational Collaborative Lifecycle Management versions,
-Dcom.ibm.java.diagnostics.healthcenter.agent parameter may not be
found in the server.startup, in this case the update is not needed and
you can start using your server.
Windows:
Comment out the line (where HEALTHCENTER_OPTS parameter located) by
inserting "rem " at the beginning of the line:
Before modification:
set HEALTHCENTER_OPTS=-agentlib:healthcenter ...
After modification:
rem set HEALTHCENTER_OPTS=-agentlib:healthcenter ...
Linux:
Comment out the line (where HEALTHCENTER_OPTS parameter located) by
inserting "# " at the beginning of the line:
Before modification:
export HEALTHCENTER_OPTS="-agentlib:healthcenter ...
After modification:
# export HEALTHCENTER_OPTS="-agentlib:healthcenter ...
o Start the server. Navigate to the Server directory in your Rational product
installation path and run this script: server.startup.
STEPS TO APPLY THE REMEDIATION:
1. Optionally, upgrade your products to an Extended Maintenance Release
version: 5.0.2 or 6.0.2. Or optionally, upgrade to the latest 6.0.x 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.
o For the 6.0.6 release: JRE 7.1.4.30(<product>-JavaSE-JRE-7.1SR4FP30) or JRE
8.0.5.20(<product>-JavaSE-JRE-8.0SR15FP20)
o Rational Collaborative Lifecycle Management 6.0.6
- For the 6.0.2 release: JRE 7.1.4.30(<product>-JavaSE-JRE-7.1SR4FP30)
- Rational Collaborative Lifecycle Management 6.0.2
- For the 5.x releases:
- IBM SDK Java(TM) Technology Edition, Version 6 is no longer supported
on distributed platforms. IBM Collaborative Lifecycle Management
(CLM) products version 5.x use Java 6 and are affected. IBM highly
recommends customers to upgrade to Extended Maintenance Release
6.0.2 for those wishing the stability and support of an EMR
release, or to the latest 6.0.x version for those desiring the
latest features. For additional details review: Impact to CLM 5.x
suite of products due to Java 6 EOS
4. Upgrade your JRE following the instructions in the link below:
How to update the IBM SDK for Java of IBM Rational products based on version
3.0.1.6 or later of IBM's Jazz technology
5. Navigate to the server directory in your Rational product installation path,
and go to jre/lib/security path.
6. Optionallly, 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
Workarounds and Mitigations
None
Important Note
IBM strongly suggests that all System z customers be subscribed to the System z
Security Portal to receive the latest critical System z security and integrity
service. If you are not subscribed, see the instructions on the System z
Security web site. Security and integrity APARs and associated fixes will be
posted to this portal. IBM suggests reviewing the CVSS scores and applying all
security or integrity fixes as soon as possible to minimize any potential risk.
