|Type||Denial of service|
An issue has been found in Apache HTTPd >= 2.4.34 and <= 2.4.38. When HTTP/2 was enabled for a http: host or H2Upgrade was enabled for h2 on a https: host, an Upgrade request from http/1.1 to http/2 that was not the first request on a connection could lead to a misconfiguration and crash. A server that never enabled the h2 protocol or that only enabled it for https: and did not configure the "H2Upgrade on" is unaffected by this.
