CVE-2019-9515 | 12 Apache, Apple, Canonical and 9 more | 24 Traffic Server, Mac Os X, Swiftnio and 21 more | 2024-02-04 | 7.8 HIGH | 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. | |||||
CVE-2019-9512 | 5 Apache, Apple, Canonical and 2 more | 6 Traffic Server, Mac Os X, Swiftnio and 3 more | 2024-02-04 | 7.8 HIGH | 7.5 HIGH |
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. | |||||
CVE-2019-9511 | 12 Apache, Apple, Canonical and 9 more | 22 Traffic Server, Mac Os X, Swiftnio and 19 more | 2024-02-04 | 7.8 HIGH | 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. |
