containerd CRI plugin: — image-config `LABEL` flows to restart-monitor `binary://` logger: host-root command execution from an image pull
containerd is an open-source container runtime. In versions prior to 1.7.33, 2.3.2, 2.2.5, 2.1.9, and 2.0.10 the CRI plugin propagates labels from an image config (LABEL instruction in Dockerfile) to a container without validation. This may result in executin…
