possible that the document may be removed without our knowledge.

^2 In BIG-IP 13.1.0 and later, you can update APM client components
independently from BIG-IP software. APM Clients 7.1.5, which is bundled with

column, you can eliminate this vulnerability by upgrading to a version listed
in the Fixes introduced in 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
