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-2019-9518 11 Apache, Apple, Canonical and 8 more 26 Traffic Server, Mac Os X, Swiftnio and 23 more 2025-01-14 7.5 High
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.
