containerd CRI — image-config LABEL flows to restart-monitor binary:// logger: host-root command execution from an image pull
Impact
A bug was found in containerd where the CRI plugin propagates labels from an image config (LABEL instruction in Dockerfile) to a container without validation. This may result in executing an arbitrary command on the host, via a plugin that consumes container labels for some operations.
Patches
This bug has been fixed in the following containerd versions:
- 2.3.2
- 2.2.5
- 2.1.9
- 2.0.10
- 1.7.33
Users should update to these versions to resolve the issue.
Workarounds
Ensure that only trusted images are used.
