CVE-2019-9518 Open this link in a new tabHow to fix?
Upgrade Debian:11 trafficserver to version 8.0.5+ds-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream trafficserver package and not the trafficserver package as distributed by Debian.
See How to fix? for Debian:11 relevant fixed versions and status.
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.
