CVE-2016-8740 is a resource-allocation denial-of-service vulnerability in Apache HTTP Server mod_http2 versions 2.4.17 through 2.4.23. When HTTP/2 support is enabled through a Protocols configuration containing h2 or h2c, mod_http2 incompletely enforces LimitRequestFields while processing HTTP/2 request headers. Crafted requests using excessive CONTINUATION frames can cause unbounded request-header memory consumption.
