Description

On BIG-IP 13.1.0-13.1.0.7 a remote attacker using undisclosed methods against virtual servers configured with a Client SSL or Server SSL profile that has the SSL Forward Proxy feature enabled can force the Traffic Management Microkernel (tmm) to leak memory. As a result system memory usage increases over time which may eventually cause a decrease in performance or a system reboot due to memory exhaustion.
