CVE-2018-11763

Priority
Description
In Apache HTTP Server 2.4.17 to 2.4.34, by sending continuous, large
SETTINGS frames a client can occupy a connection, server thread and CPU
time without any connection timeout coming to effect. This affects only
HTTP/2 connections. A possible mitigation is to not enable the h2 protocol.
