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.

Mitigation

None. To avoid vulnerability exposure, F5 recommends removing the limited directive from ntpd restriction statements.

Impact of action: Various F5 product features rely on proper date and time configuration; ensure that any modifications to the ntpd configuration are compatible with your environment.
