Description

HTTP/2 incoming headers exceeding the limit are temporarily buffered in nghttp2 in order to generate an informative HTTP 413 response. If a client does not stop sending headers, this leads to memory exhaustion.. A vulnerability was found in how Apache httpd implements the HTTP/2 protocol. There are insufficient limitations placed on the amount of CONTINUATION frames that can be sent within a single stream. This issue could allow an unauthenticated remote attacker to send packets to vulnerable servers, which could use up memory resources to cause a Denial of Service.
