Affected Products and Versions

IBM DB2 10.1, Accessories Suite for Linux, UNIX and Windows
IBM DB2 10.5, Accessories Suite for Linux, UNIX and Windows

Remediation/Fixes

Check to see if either <DB2_install_dir>/db2tss/Stellent or <instance home>/db2tss/Stellent are installed directories.  If neither of these directories exist, then the environment is not vulnerable to this risk.
 
If you do see the Stellent directory then check the following:

Check the accSuiteRelease.properties file located in <DB2_install_dir>/db2tss. If the accSuiteRelease.properties file does not exist, or if the properties file exists, but the version number in the properties file is less than V2.3.0, reinstallation of the latest release is necessary:

1. Download DB2 10.1 Accessories Suite or DB2 10.5 Accessories Suite from https://www-01.ibm.com/marketing/iwm/iwm/web/reg/pick.do?source=swg-dm-db2accsuite&lang=en_US and extract.
2. Stop the text search service: db2ts stop for text
3. Run the installer to upgrade your existing setup
4. Verify in db2_install_dir/db2tss/accSuiteRelease.properties or db2instance_home/db2tss/accSuiteRelease.properties that the new version number is 2.3.0
