  "details" : [ "In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service. The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of 14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at 100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame and the number of settings entries are large (e.g., > 32), then drop the connection.", "A resource consumption vulnerability was found in nghttp2. This flaw allows an attacker to repeatedly construct an overly large HTTP/2 SETTINGS frame with a length of 14,400 bytes that causes excessive CPU usage, leading to a denial of service." ],
