Oracle Linux: CVE-2019-9514: ELSA-2019-4273: container-tools:1.0 security update (IMPORTANT) (Multiple Advisories)

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.
A flaw was found in HTTP/2. Using HEADER frames with invalid HTTP headers and queuing of response RST_STREAM frames, an attacker could cause a flood resulting in unbounded memory growth. The highest threat from this vulnerability is to system availability.
