### 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.
