"Undisclosed SSL traffic to a virtual server configured with a Client
SSL profile may cause TMM to fail and restart. The Client SSL profile
must have session tickets enabled and use DHE cipher suites to be
affected. This only impacts the data plane, there is no impact to the
control plane. (CVE-2019-6629)

Impact

Traffic processing is disrupted while the Traffic Management
Microkernel (TMM) restarts. If the affected F5 device is configured as
part of a device group, the system will trigger a failover to the peer
device.");
