Remediation/Fixes

IMPORTANT CONSIDERATIONS:

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.

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 July 2017 CPU to get the WAS 
remediation .

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:

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

3.2. 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 ...

3.3.

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. Upgrade your products to a supported version: 4.0.7, 5.0.2, 6.0.2, or 6.0.4
2. Apply the latest ifix for your installed version.
3. Obtain the July 2017 CPU update for the IBM Java SDK.

Based on version installed, obtain the latest ifixes (recommended), and the 
below indicated java from:

For the 6.0.2 and 6.0.4 releases: JRE 7.1.4.10 (<product>-JavaSE-JRE-7.1SR4FP10)
  Rational Collaborative Lifecycle Management 6.0.2

For the 5.x releases: JRE 6.0.16.50 (<product>-JavaSE-JRE-6.0SR16FP50)
  Rational Collaborative Lifecycle Management 5.0.2

For the 4.x releases: JRE 6.0.16.50 (<product>-JavaSE-JRE-6.0SR16FP50)
  Rational Collaborative Lifecycle Management 4.0.7

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
