Affected Products and Versions
IBM Rational Synergy 7.2.1 7.2.1.5.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-6.0.16.50- <platform>
Where <V.R.M.F> = release & <platform> = operating system
o Rational Synergy 7.2.1 (uses 7.2.1.5 release designation)
Example: 7.2.1.5-Rational-RATISYNE-JavaSE-SDK-6.0.16.50-Linux
o Rational Synergy 7.2.0 (uses 7.2.0.7 release designation)
Example: 7.2.0.7-Rational-RATISYNE-JavaSE-SDK-6.0.16.50-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 the output version is SR16 FP50 or greater than SR16 FP50, 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 pxi3260sr16fp20-20160111_01(SR16 FP20))
IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 Linux x86-32
jvmxi3260sr16fp20-20151221_282799 (JIT enabled, AOT enabled)
