Security Advisory Description

Under limited circumstances, connections handled by a virtual server with an
associated SOCKS profile may not be properly cleaned up, potentially leading to
resource starvation. CVE-2017-0303

Impact

Connections may remain in the connection table that you can only remove by
restarting the Traffic Management Microkernel (TMM). Over time, the BIG-IP
system may be unable to process further connections.

Security Advisory Status

F5 Product Development has assigned ID 641360 (BIG-IP) to this vulnerability.

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 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.

To determine the necessary upgrade path for your BIG-IQ system, you should
understand the BIG-IQ product offering name changes. For more information,
refer to K21232150: Considerations for upgrading BIG-IQ or F5 iWorkflow systems
