Remediation/Fixes

The IBM Jazz Team Server based Applications bundle different versions of IBM WebSphere Application Server and IBM WebSphere Application Server Liberty with the available versions of the products, and in addition to the bundled version some previous versions of WAS are also supported. For a remediation follow the WAS security bulletin appropriately:

Review the Security Bulletin: Code execution vulnerability in WebSphere Application Server (CVE-2016-5983) for vulnerability details.
Check the version of WAS, if any, that your deployment is actually using, and compare it against the list of affected versions in the security bulletin.
Review the Remediation/Fixes section in the Security Bulletin: Code execution vulnerability in WebSphere Application Server (CVE-2016-5983) for available fixes in the version that you are using.

NOTE: When installing the fixed WAS Liberty package use <JazzInstallLocation>/server/liberty/wlp as the location of the WAS Liberty installation, where <JazzInstallLocation> is the root folder of your CLM installation.
