Affected Products and Versions

Remediation/Fixes

IBM strongly recommends addressing the vulnerability now by upgrading ITNCM version to 6.4.2 Fix Pack 20 (6.4.2.20) with the below specified Java version(8.0.8.20).

Note that only standalone worker servers and compliance servers (i.e. those which are not co-located on the same machine as a presentation server) need to have their JRE updated. To update the Java Runtime Environment (JRE), complete the following steps.

1. Locate the appropriate IBM JRE for your operating system on the IBM Fix Central website.

AIX: IBM Java 8.0.8.20 for AIX

Linux: IBMJava 8.0.8.20 for 64-bit Linux

zLinux: IBM Java 8.0.8.20 for Linux for z/OS

2. Download version 8.0.8.20 in archive, rather than binary, form and install it.

3. Back up the directory $NCMHOME/jre.

4. Stop all running processes of the compliance or worker server by using the “itncm.sh stop” command.

5. Delete the contents of the $NCMHOME/jre/bin and $NCMHOME/jre/lib directory.

6. Copy the contents of the bin and lib directories from the JRE that you installed in step 2 to $NCMHOME/jre/bin and $NCHOME/jre/lib, respectively.

7. Restart the compliance or worker server by using the “itncm.sh start” command.

To roll back to the previous Netcool Configuration Manager compliance or worker server JRE, restore the backup that you made in step 3. Perform the rollback, then perform steps 4 to 7 again.
