TITLE

HTTP/2 implementations do not robustly handle abnormal traffic and resource exhaustion

DESCRIPTION

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. Multiple HTTP/2 implementations are vulnerable to a variety of denial-of-service (DoS) attacks. HTTP/2 is the second version of the hypertext transfer protocol, which is mainly used to ensure the communication between the client and the server. A resource management error vulnerability exists in HTTP/2. An attacker could exploit this vulnerability to cause a denial of service.
