Security Advisory Recommended Actions

If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Versions known to be not vulnerable column. 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. For more information,
refer to K21232150: Considerations for upgrading BIG-IQ or F5 iWorkflow
systems.
