Remediation/Fixes
IBM recommends updating the FSM SMIA configuration tool using the instructions referenced in this table.
IMPORTANT: Before installing a SMIA iFix you need to determine the version that is currently installed. To determine the SMIA version level installed on the FSM log into your FSM Web-based UI and navigate to the Home page and Applications tab. The version is listed next to the "SMIA Configuration Tool" link.
- If your SMIA version is less than 14.0.2, update your FSM using the instructions listed in this Security Bulletin (http://www-01.ibm.com/support/docview.wss?uid=isg3T1024508), restart the FSM and then install the iFix listed in this table.
- If your version is 14.0.2 or greater, then install the iFix listed in this table.
