Remediation/Fixes

In order to fix this vulnerability, java is to be upgraded to 8.0.6.30 for TADDM versions 7.3.0.5 - 7.3.0.8 or to 7.0.10.85 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 - 7.3.0.8 (JAVA 8), if the above command output contains "SR6 FP10" or "8.0.6.10" or Higher as build in Java(TM) SE Runtime Environment information, apply efix for the new IBM SDK only, efix_jdk8.0.6.30_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 FP80" or "7.0.10.80"  or Higher as build in Java(TM) SE Runtime Environment information, apply efix for the new IBM SDK only, efix_jdk7.0.10.85_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:  For TADDM 7.3.0.5 - 7.3.0.8 (JAVA 8), request for efix "customJDK8.0.6.10" and For TADDM 7.3.0.3 - 7.3.0.4 (JAVA 7), request for efix "customJDK7.0.10.65", 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 -1 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.
