A flaw was found in the mod_http2 module of 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. This vulnerability can exhaust worker resources in the server, similar to the well-known “slow loris” attack pattern.
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
