Description Laura Pardo 2019-01-22 21:43:27 UTC
A flaw was found in HTTP/2 (mod_http2) connections in Apache HTTP Server httpd 2.4.17 to 2.4.37. A DoS can be triggered by sending request bodies in a slow loris way to plain resources, the h2 stream for that request unnecessarily occupied a server thread cleaning up that incoming data.
