Description
In certain proxy configurations, a denial of service attack against Apache HTTP Server versions 2.4.26 through to 2.4.63 can be triggered by untrusted clients causing an assertion in mod_proxy_http2.
Configurations affected are a reverse proxy is configured for an HTTP/2 backend, with ProxyPreserveHost set to "on".
An assertion failure flaw was found in Apache httpd. Untrusted clients can send inputs that trigger an assertion failure in the mod_proxy_http2 module, which likely results in an Apache HTTP server crash or denial of service (DoS).
