| CVE-2019-9511 | 12 Apache, Apple, Canonical and 9 more | 29 Traffic Server, Mac Os X, Swiftnio and 26 more | 2025-01-14 | 7.5 High |
| Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. | ||||
| CVE-2019-9514 | 13 Apache, Apple, Canonical and 10 more | 44 Traffic Server, Mac Os X, Swiftnio and 41 more | 2025-01-14 | 7.5 High |
| 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. | ||||
| CVE-2019-9515 | 12 Apache, Apple, Canonical and 9 more | 36 Traffic Server, Mac Os X, Swiftnio and 33 more | 2025-01-14 | 7.5 High |
| 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. | ||||
