^1The CVSSv3 score link takes you to a resource outside of AskF5, and it is
possible that the document may be removed without our knowledge.

^2The specified products contain the affected code. However, F5 identifies the
vulnerability status as Not vulnerable because the attacker cannot exploit the
code in default, standard, or recommended configurations.

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 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

To mitigate this vulnerability, you can disable image optimisation in your web
acceleration policy. 

Impact of action: When you disable image optimization, you may use more
bandwidth because you are sending less optimized images to clients; however,
you may also lower CPU usage because you are not reprocessing images.

For more information, refer to the Accelerating Images with Image Optimization
chapter of the BIG-IP Acceleration: Concepts manual.

Note: For information about how to locate F5 product manuals, refer to
K98133564: Tips for searching AskF5 and finding product documentation.
