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 |
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(TM) 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)
