Security Bulletin: Multiple vulnerabilities in IBM Java Runtime affect IBM Platform Symphony and IBM Spectrum Symphony

Remediation/Fixes

Applicability

• Operating systems: Linux x64

• Cluster type: Single grid cluster

Prerequisite

To install or uninstall the .rpm packages for IBM Spectrum Symphony 7.1.2 and 7.2.0.2, you must have root permission and RPM version 4.2.1 or later must be installed on the host.

Before installation

1. Log on to the mamagement host as the cluster administrator.

2. Disable your applications, stop services, and shut down the cluster:

> source profile.platform

> soamcontrol app disable all

> egosh service stop all

> egosh ego shutdown all

3. Back up or uninstall the existing JRE on all management hosts:

For Platform Symphony 7.1 Fix Pack 1 and 7.1.1, back up the JRE folder (under $EGO_TOP/jre/<EGO_version>/linux-x86_64/). For example, in a Platform Symphony 7.1.1 cluster, back up the JRE folder at $EGO_TOP/jre/3.3/linux-x86_64/.

For IBM Spectrum Symphony 7.1.2 and 7.2.0.2, uninstall the existing JRE.

1. Query the existing JRE package and uninstall it from the dbpath location, for example:

> rpm -qa --dbpath /tmp/rpm |grep egojre

egojre-1.8.0.3-408454.x86_64

> rpm -e egojre-1.8.0.3-408454.x86_64 --dbpath /tmp/rpm --nodeps

2. For IBM Spectrum Symphony 7.2.0.2, remove the leftover link under the jre folder, for example:

> rm -rf $EGO_TOP/jre/8.0.5.0

Install this interim fix

1. Log on each management host as the cluster administrator and replace your current JRE folder with the files in this interim fix.

For Platform Symphony 7.1 Fix Pack 1 and 7.1.1, remove the files in the existing JRE folder and extract the interim package to the JRE folder on all hosts.

For example, in a Platform Symphony 7.1.1 cluster, enter the following commands:

> rm -rf $EGO_TOP/jre/3.3/linux-x86_64/*

> tar zxfo symSetup_jre8sr5fp21_linux-64_build502764.tar.gz -C $EGO_TOP/jre/3.3/linux-x86_64

For IBM Spectrum Symphony 7.1.2 and 7.2.0.2, use the same dbpath and prefix as the installation, for example:

> rpm –ivh --dbpath /tmp/rpm --prefix /opt/platform egojre-1.8.0.521.x86_64.rpm

2. Delete all subdirectories and files in the GUI work directory:

> rm -rf $EGO_TOP/gui/work/*

> rm -rf $EGO_TOP/gui/workarea/*

NOTE: If you configured the WLP_OUTPUT_DIR parameter and APPEND_HOSTNAME_TO_WLP_OUTPUT_DIR is set to true in the $EGO_CONFDIR/conf/wlp.conf file, you must clean up the $WLP_OUTPUT_DIR/webgui_hostname/gui/workarea/ directory.

3. Launch your browser and clear the browser cache.

4. Log on to the management host as the cluster administrator, start the cluster and enable your applications:

> source profile.platform

> egosh ego start all

> soamcontrol app enable <appName>

Verify the installation

• For Platform Symphony 7.1 Fix Pack 1, the following example shows output for the java -version command:

> $EGO_TOP/jre/3.1/linux-x86_64/bin/java -version

java version "1.8.0_181"

• For IBM Spectrum Symphony 7.1.2, the following example shows output for the rpm -qa command:

> rpm -qa --dbpath /tmp/rpm |grep egojre

egojre-1.8.0.521-502764.x86_64

• For IBM Spectrum Symphony 7.2.0.2, the following example shows output for the rpm -qa command:

> rpm -qa --dbpath /tmp/rpm |grep egojre

egojre-8.0.5.21-502764.x86_64

Uninstallation

If required, follow these instructions to uninstall this interim fix in your cluster:

1. Log on to the management host as the cluster administrator.

2. Disable your applications, stop services, and shut down the cluster:

> source profile.platform

> soamcontrol app disable all

> egosh service stop all

> egosh ego shutdown all

3. Log on each management host as the cluster administrator and restore the JRE folder from your backup.

For Platform Symphony 7.1 Fix Pack 1 and 7.1.1, restore your backup to the $EGO_TOP/jre/<EGO_version>/linux-x86_64/ folder. For example, in a Platform Symphony 7.1.1 cluster, restore your backup to the $EGO_TOP/jre/3.3/linux-x86_64/ folder.

For IBM Spectrum Symphony 7.1.2 and 7.2.0.2, uninstall the existing JRE, then install the old one:

1. Uninstall the JRE fix, for example:
   > rpm -e egojre-1.8.0.521-502764.x86_64 --dbpath /tmp/rpm/ --nodeps

2. For IBM Spectrum Symphony 7.2.0.2, remove the leftover link under the jre folder, for example:
   > rm -rf $EGO_TOP/jre/8.0.5.21

3. Extract the egojre .rpm package from the .bin installation package, for example, for IBM Spectrum Symphony 7.1.2:
   > sym-7.1.2.0_x86_64.bin --extract /opt/extract

4. Reinstall the old JRE package. Use the same dbpath and prefix as the installation, for example:
   > rpm -ivh --dbpath /tmp/rpm --prefix /opt/platform /opt/extract/egojre-1.8.0.3.x86_64.rpm

4. Delete all subdirectories and files in the GUI work directory:

> rm -rf $EGO_TOP/gui/work/*

> rm -rf $EGO_TOP/gui/workarea/*

NOTE: If you configured the WLP_OUTPUT_DIR parameter and APPEND_HOSTNAME_TO_WLP_OUTPUT_DIR is set to true in the $EGO_CONFDIR/conf/wlp.conf file, you must clean up the $WLP_OUTPUT_DIR/webgui_hostname/gui/workarea/ directory.

5. Launch your browser and clear the browser cache.

6. Log on to the management host as the cluster administrator, start the cluster and enable your applications:

> source profile.platform

> egosh ego start all

> soamcontrol app enable <appName>
