FKIE_CVE-2018-5527
Vulnerability from fkie_nvd - Published: 2018-06-27 20:29 - Updated: 2026-06-17 02:00
Severity
Summary
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.
