Apache HTTP Server is vulnerable to a denial of service, caused by the failure to check or limit the use of HTTP/2 CONTINUATION frames that can be sent within a single stream. By sending a stream of CONTINUATION frames that will not be appended to the header list in memory but will still be processed and decoded by the server or will be appended to the header list, a remote attacker could exploit this vulnerability to cause an out of memory (OOM) crash.

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.
