github.com/nghttp2/nghttp2/ is vulnerable to Denial of Service (DoS). The vulnerability is due a lack of frame count restrictions, which can result in nghttp2 reading an unbounded number of HTTP/2 CONTINUATION frames even after the stream is reset to keep HPACK context in sync. An attacker can exploit this vulnerability to cause Denial of Service by flooding the webserver with CONTINUATION frames.
