Affected Products and Versions

Remediation/Fixes

In order to fix this vulnerability, Java needs to be upgraded to 8.0.7.15 for TADDM versions 7.3.0.5 - 7.3.0.9 or to 7.0.11.15 for TADDM versions 7.3.0.3 - 7.3.0.4.

Check java version installed on TADDM servers using the below command:

$COLLATION_HOME/external/<jdk- folder according to OS>/bin/java -version

• For TADDM 7.3.0.5 - 7.3.0.9 (JAVA 8), if the above command output contains**“SR6 FP10”**or “8.0.6.10” or higher as build in Java™ SE Runtime Environment information, apply efix for the new IBM SDK only,**efix_jdk8.0.7.15_FP9211123.zip **given in Table-1 below.
• For TADDM 7.3.0.3 - 7.3.0.4 (JAVA 7), if the above command output contains**“SR10 FP65”**or “7.0.10.65” or higher as build in Java™ SE Runtime Environment information, apply efix for the new IBM SDK only,efix_jdk7.0.11.15_FP420171214.zip given in Table-1 below.
• For TADDM 7.3.0.0 - 7.3.0.2 (JAVA 7), Please upgrade to IBM Tivoli Application Dependency Discovery Manager Version 7.3.0.3 or later (Preferably the latest release 7.3.0.10). For TADDM version 7.3.0.10, there is no need to apply the above mentioned Java e-fixes. For other lower TADDM versions, you need apply the above mentioned Java e-fixes.
• For all other cases:

The remediation consists of 2 steps:

1. Please contact IBM Support and open a case for a custom version of eFix “customJDK8.0.6.10” as this efix involves TADDM code changes. Include the current eFix level (ls -rlt etc/efix*), TADDM version and a link to this bulletin.
2. Along with the above efix, apply efix for the new IBM SDK as per TADDM version given in table below.

Table-1:

Please review the eFix readme in etc/efix_readme.txt. The fixes for the respective FixPack(s) can be downloaded and applied directly.
