K46011592 : HTTP/2 Empty Frames Flood vulnerability CVE-2019-9518

Security Advisory Description

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. (CVE-2019-9518)
