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:
   * * Stop the server: Navigate to the Server directory in your Ratonal product installation path and run this script: server.shutdown
   • 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 …

    *       * **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.

• *       * 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-8.0SR5FP11_**) 
  * [_Rational Collaborative Lifecycle Management 6.0.5_](<http://www.ibm.com/support/fixcentral/swg/selectFixes?parent=ibm~Rational&product=ibm/Rational/Rational+Collaborative+Lifecycle+Management+Solution&release=6.0.5&platform=All&function=all>)
  

  • For the 6.0.2 release: JRE 7.1.4.20**(<product>-JavaSE-JRE-7.1SR4FP20**)
    • Rational Collaborative Lifecycle Management 6.0.2
  • 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](<http://www.ibm.com/support/docview.wss?uid=swg22015069>)
    

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
