Descriptions
Some HTTP/2 implementations are vulnerable to ping floods, potentially leading to a denial of service. The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
Algunas implementaciones de HTTP / 2 son vulnerables a las inundaciones de ping, lo que puede conducir a una denegación de servicio. El atacante envía pings continuos a un par HTTP / 2, haciendo que el par construya una cola interna de respuestas. Dependiendo de cuán eficientemente se pongan en cola estos datos, esto puede consumir un exceso de CPU, memoria o ambos.
A flaw was found in HTTP/2. Using PING frames and queuing of response PING ACK frames, a flood attack could occur resulting in unbounded memory growth. The highest threat from this vulnerability is to system availability.
