Description
When a TCP profile with Multipath TCP (MPTCP) enabled is configured on a virtual server, undisclosed traffic along with conditions beyond the attacker's control can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
