[3.9] apache2: DoS for HTTP/2 connections by continuous SETTINGS (CVE-2018-11763)
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.
Fixed in Version:
Apache httpd 2.4.35
