Important: golang security update (Amazon Linux 2)

Published Aug 23, 2019 · Updated Aug 27, 2019

Summary

Package updates are available for Amazon Linux 2 that fix the following vulnerabilities: CVE-2019-9514: 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. 1735744: CVE-2019-9514 HTTP/2: flood using HEADERS frames results in unbounded memory growth CVE-2019-9512: 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. 1735645: CVE-2019-9512 HTTP/2: flood using PING frames results in unbounded memory growth
