CVE-2018-5527 (GCVE-0-2018-5527)

Vulnerability from cvelistv5 – Published: 2018-06-27 20:00 – Updated: 2024-09-16 19:14

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.

Severity
