IBM Rational Lifecycle Integration Adapter for HP ALM 1.1.2 and 1.1.2.1

Remediation/Fixes

The fix is available on Fix Central.

You should verify applying this fix does not cause any compatibility issues. The fix disables RC4 stream cipher by default. If you change the default setting after applying the fix, you will expose yourself to the attack described above. IBM recommends that you review your entire environment to identify other areas where you have enabled the RC4 stream cipher and take appropriate mitigation and remediation actions.

To update IBM Rational Lifecycle Integration Adapter with a corrected JRE, follow the instructions below. Depending on how you deployed the products, and depending on your usage scenarios, you might need to upgrade the IBM SDK, Java Technology Edition in IBM WebSphere Application Server and Apache Tomcat. Be sure to upgrade all the components that you use in your deployment uses.

NOTE: IBM SDK, Java Technology Edition is only included in IBM Rational Lifecycle Integration Adapter version 1.1.2 and 1.1.2.1. Previous versions of the Rational Lifecycle Integration Adapter Standard Edition HP Adapter were released as WAR files only. Please consult with the application server documentation for updating the IBM SDK, Java Technology Edition.

**Upgrading the JRE for aWebSphere Application Server installation **If your products are deployed on WebSphere Application Server, Java SDK Upgrade Policy for the IBM WebSphere Application Server lists IBM SDK, Java Technology Edition upgrades that are available. Also check the Product Security Incident Response Blog for any recent security bulletins for WebSphere Application Server that may have fixpacks or interim fixes for the JRE.

Upgrading theIBM SDK, Java Technology Edition** for a Tomcat installations**

1. Stop the Rational Lifecycle Integration Adapter server.

Note: The applications may be running in different application server instances or using a delegated converter.

2. Go to the original installation directory, and rename the /jre folder

<InstallDir>/server/jre

to

<InstallDir>/server/jre-Original

This ensures that the original JRE is kept as a backup in the event a restore is required._

_Example (Linux): mv <OrigInstallDir>/server/jre <OrigInstallDir>/server/jre-Original

3. Extract the new JRE archive provided by support to the Installation directory.

Example (Linux): unzip <newInsallZip> -d <InstallDir>/server/

4. Remove the Apache Tomcat temporary files in the following directories:

<OrigInstallDir>/server/tomcat/temp <OrigInstallDir>/server/tomcat/work/Catalina/localhost

5. Restart the Rational Lifecycle Integration Adapter server
