Vulnerability 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.
Mitigation
None. F5 recommends removing the TCP analytics profile from the virtual server
with the associated FastL4 profile. Supplemental Information
