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 theVersions 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.
Mitigation
To mitigate this vulnerability, you can disable TMM fast forward flows. To do so, perform the following procedure:
Impact of workaround: Performing the following procedure requires that you reboot the BIG-IP system. The**tmm.ffwd.enable **database variable allows a TMM at 100 percent capacity to forward connections to a TMM under less intensive CPU load.
tmsh modify sys db tmm.ffwd.enable value false
reboot
