Amazon Linux 2 Security Advisory: ALAS-2019-1272
Advisory Release Date: 2019-08-23 03:20 Pacific
Advisory Updated Date: 2019-08-27 21:53 Pacific
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-2019-9512)
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-2019-9514)
