CVE-2019-9515 [HIGH] CWE-400 CVE-2019-9515: Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of s Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently th

CVE-2019-9517 [HIGH] CWE-400 CVE-2019-9517: Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially lead Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire.
