Remediation/Fixes

Product

| VRMF| Remediation/First Fix
—|—|—
Rational Synergy| 7.2.0.x and 7.2.1.x| 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-6.0.16.15-<platform> **

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

o Rational Synergy 7.2.1 (uses 7.2.1.4 release designation)
Example: 7.2.1.4-Rational-RATISYNE-JavaSE-SDK-6.0.16.15-Linux

o Rational Synergy 7.2.0 (uses 7.2.0.7 release designation)
Example: 7.2.0.7-Rational-RATISYNE-JavaSE-SDK-6.0.16.15-Windows

3. Follow the steps in the Install instructions to replace the JRE.

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 in the output version is greater than SR16 FP15 or if it is SR16 FP15, It implies the run area has jre version that addresses these security vulnerabilities.

Example:-
Java™ SE Runtime Environment (build pwi3260sr16fp15-20151106_01(SR16 FP15))
IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 Windows 7 x86-32 jvmwi3260sr16fp15-20
