A flaw was found in httpd. This flaw allows an attacker opening an HTTP/2 connection with an initial window size of 0 to block handling of that connection indefinitely in the Apache HTTP Server. This vulnerability can exhaust worker resources in the server, similar to the well-known "slow loris" attack pattern.
