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? Java
    SDK affects WebSphere Application Server January 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 6.0.5 release: JRE 7.1.4.20(<product>-JavaSE-JRE-7.1SR4FP20
            ) or JRE 8.0.5.11(<product>-JavaSE-JRE-8.0SR5FP1)
                Rational Collaborative Lifecycle Management 6.0.5
          o For the 6.0.2 release: JRE 7.1.4.20(<product>-JavaSE-JRE-7.1SR4FP20
            )
                Rational Collaborative Lifecycle Management 6.0.2
          o For the 5.x releases:
                IBM SDK Java? 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. Open java.security file using prefered text editor (e.g., Notepad for
Windows or Vim Editor for Linux) and remove MD5 option from the
jdk.jar.disabledAlgorithms parameter set:

  * Before modification:

jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024

  * After modification:

jdk.jar.disabledAlgorithms=MD2, RSA keySize < 1024
