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.

Affected configurations

• f5 big-ip access policy manager (>= 13.0.0 <= 13.1.0.7) • f5 big-ip advanced firewall manager (>= 13.0.0 <= 13.1.0.7) • f5 big-ip analytics (>= 13.0.0 <= 13.1.0.7) • f5 big-ip application acceleration manager (>= 13.0.0 <= 13.1.0.7) • f5 big-ip application security manager (>= 13.0.0 <= 13.1.0.7) • f5 big-ip domain name system (>= 13.0.0 <= 13.1.0.7) • f5 big-ip edge gateway (>= 13.0.0 <= 13.1.0.7) • f5 big-ip global traffic manager (>= 13.0.0 <= 13.1.0.7) • f5 big-ip link controller (>= 13.0.0 <= 13.1.0.7) • f5 big-ip local traffic manager (>= 13.0.0 <= 13.1.0.7) • f5 big-ip policy enforcement manager (>= 13.0.0 <= 13.1.0.7) • f5 big-ip webaccelerator (>= 13.0.0 <= 13.1.0.7) • f5 big-ip websafe (>= 13.0.0 <= 13.1.0.7)
