"An undisclosed type of responses may cause TMM to restart, causing an
interruption of service when 'SSL Forward Proxy' setting is enabled in

Impact
If the SSL Forward Proxy option is enabled on both the Client and
Server SSL profile assigned to a BIG-IP virtual server, an attacker
may be able to cause the Traffic Management Microkernel (TMM) to
restart, resulting in traffic disruption."
