NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-0876. ( CVE-2016-5300) Impact An attacker may be able to cause a denial-of-service (DoS) attack via crafted identifiers in an XML document. Security Advisory Status F5 Product Development has assigned ID 617273 (BIG-IP), ID 617964 (BIG-IQ/F5 iWorkflow), ID 618243 (Enterprise Manager), and ID 528541 (ARX) to this vulnerability. Additionally, BIG-IP iHealth may list Heuristic H624219 on the Diagnostics > Identified > Medium screen.

If the table lists only an older version than what you are currently running, or does not list a non-vulnerable version, then no upgrade candidate currently exists. To determine the necessary upgrade path for your BIG-IQ system, you should understand the BIG-IQ product offering name changes.
