Security Advisory Recommended Actions
If you are running a version listed in the Versions known to be vulnerable column, you can eliminate this vulnerability by installing a version listed in the Fixes introduced in column. If the Fixes introduced in column does not list a version for your branch, then no update candidate currently exists for that branch and F5 recommends that you upgrade to a version with the fix (refer to the tables).
If the Fixes introduced in column lists a version prior to the one you are running, in the same branch, then your version should have the fix.
Mitigation
Do not process or handle data from untrusted sources.
