Affected Products and Versions

Remediation/Fixes

In order to fix this vulnerability, java is to be upgraded to 8.0.7.0 for TADDM versions 7.3.0.5 - 7.3.0.9 or to 7.0.11.0 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_jdk8.0.7.0_FP8201126.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_jdk7.0.11.0_FP420171214.zip given in Table-1 below.
• 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. Alongwith the above efix, apply efix for the new IBM SDK as per TADDM version given in table below.

Table-1:

Please get familiar with the eFix readme in etc/efix_readme.txt. These fixes for the respective FixPack(s) can be downloaded and applied directly.
