CVSS: 7.8EPSS: 2%CPEs: 44EXPL: 0CVE-2019-9515 – Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service
https://notcve.org/view.php?id=CVE-2019-9515
13 Aug 2019 — 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 this data is queued, this can consume excess CPU, memory, or both.

https://notcve.org/view.php?id=CVE-2019-9516
13 Aug 2019 — Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory.

https://notcve.org/view.php?id=CVE-2019-9517
13 Aug 2019 — 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. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both.

CVSS: 7.8EPSS: 3%CPEs: 35EXPL: 0CVE-2019-9518 – Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service
https://notcve.org/view.php?id=CVE-2019-9518
13 Aug 2019 — Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00031.html • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2019-9514
13 Aug 2019 — Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both. Algunas implementaciones de HTTP / 2 son vulnerables a una inundación de reinicio, lo que puede conducir a una denegación de servicio.
