Security Advisory Description

The BIG-IP system can experience a disruption of service when a virtual server
with an associated Client SSL profile and either an HTTP/2 or SPDY profile
receives a greater number of concurrent connections than the advertised limit.
(CVE-2017-6163)

Impact

A remote client initiating stream beyond the advertised limit can cause a
disruption of service. The Traffic Management Microkernel (TMM) data plane is
exposed to this issue; the control plane is not exposed.

Security Advisory Status

F5 Product Development has assigned ID 626360 (BIG-IP) 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 for the indicated
products/modules.

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.
