Security Advisory Description

When configuration synchronization (ConfigSync) is configured, attackers on
adjacent networks may be able to bypass the TLS protections usually used to
encrypt and authenticate connections to mcpd. (CVE-2017-6161)

Impact

This vulnerability may allow remote attackers to cause a denial-of-service
(DoS) attack by way of resource exhaustion.

Security Advisory Status

F5 Product Development has assigned ID 610255 (BIG-IP) and 638063 (Enterprise
Manager) to this vulnerability.

^1 The 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 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
.
