F5 will not develop a fix for vulnerable products that do not already have a fixed version listed in this article, and will not update this table with subsequent vulnerable releases in the associated branches. F5 recommends that you update to more recent, non-vulnerable versions whenever feasible. For more information, refer to K4602: Overview of the F5 security vulnerability response policy.

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.
