Red Hat JBossEAP: Uncontrolled Resource Consumption (CVE-2019-9518)
Description
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.. A flaw was found in HTTP/2. Using frames with an empty payload, a flood could occur that results in excessive CPU usage and starvation of other clients. The highest threat from this vulnerability is to system availability.
