Affected Products and Versions

IBM Rational Synergy 7.2.1 – 7.2.1.6.x
IBM Rational Synergy 7.2.0 – 7.2.0.7.x

Remediation/Fixes

Product

| VRMF| APAR| Remediation/First Fix
—|—|—|—
Rational Synergy| 7.2.0.x and 7.2.1.x| N/A| Replace the JRE used in Rational Synergy.

Steps to download and replace JRE in Rational Synergy:
1. Open the list of Synergy downloads on Fix Central
2. Select the SDK and Readme for Rational Synergy which applied to your release as follows:

Note: The fix will use the following naming convention: <V.R.M.F>-Rational-RATISYNE-JavaSE-SDK-6.0.16.60-<platform> **

Where<V.R.M.F> = release &<platform> = operating system**

o Rational Synergy 7.2.1 (uses 7.2.1.6 release designation)
Example: 7.2.1.6-Rational-RATISYNE-JavaSE-SDK-6.0.16.60-Linux

o Rational Synergy 7.2.0 (uses 7.2.0.7 release designation)
Example: 7.2.0.7-Rational-RATISYNE-JavaSE-SDK-6.0.16.60-Windows

3. Follow the steps in the Install instructions to replace the JRE.
Follow the steps in the HPUX_Install Instructions to replace the JRE if your Synergy Platform is on HPUX. For HP it will be 6.0.16.55
For Rational Synergy 7.1.0.x IBM recommends upgrading to a fixed, supported version/release/platform of the product.

To verify if Synergy has JRE version to address these security vulnerabilities: -
Open a command prompt **
Unix**:-
Go to $CCM_HOME/jre/bin folder
Execute ./java -version
**
Windows**:-
Go to %CCM_HOME%\jre\bin folder
Execute java -version

If the output version is SR16 FP60 or greater than SR16 FP60, it implies the run area has jre version that addresses these security vulnerabilities.
**
Example**:-
java version “1.6.0”
Java™ SE Runtime Environment (build pxi3260sr16fp60-20180213_02(SR16 FP60))
IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 Linux x86-32 jvmxi3260sr16fp60-20180125_377078 (JIT enabled, AOT enabled)
