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 October 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: 5.0.2, 6.0.2, or 6.0.5

2. Apply the latest ifix for your installed version.

3. Obtain the October 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 6.0.5 releases: JRE 7.1.4.15 
(<product>-JavaSE-JRE-7.1SR4FP15)

Rational Collaborative Lifecycle Management 6.0.2

For the 5.x releases: guidance will be published in the future.

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

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.
