Details

As written in the advisory (Markdown source, shown as plain text).

### 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. ### Credits The containerd project would like to thank Anthropic Research, in collaboration with Claude, the GKE Security Team using Gemini, and Robert Prast (@robertprast) for independently discovering and responsibly disclosing this issue in accordance with the [containerd security policy](https://github.com/containerd/project/blob/main/SECURITY.md). ### For more information If you have any questions or comments about this advisory: * Open an issue in [containerd](https://github.com/containerd/containerd/issues/new/choose) * Email us at [[email protected]](mailto:[email protected]) To report a security issue in containerd: * [Report a new vulnerability](https://github.com/containerd/containerd/security/advisories/new) * Email us at [[email protected]](mailto:[email protected])
