Affected: CleanStart: tigera-operator

Multiple security vulnerabilities affect the tigera-operator package. These issues are resolved in later releases. See references for individual vulnerability details.

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 executing an arbitrary command on the host, via a plugin that consumes container labels for some operations. This issue has been fixed in versions 1.7.33, 2.3.2, 2.2.5, 2.1.9, and 2.0.10.

### 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).

Affected: openEuler:24.03-LTS-SP3: containerd

containerd is an industry-standard container runtime with an emphasis on simplicity, robustness and portability. It is available as a daemon for Linux and Windows, which can manage the complete container lifecycle of its host system: image transfer and storage, container execution and supervision, low-level storage and network attachments, etc. Security Fix(es):

containerd is an open-source container runtime. Versions prior to 1.7.33, 2.0.10, 2.1.9, 2.2.5 and 2.3.2, contain a vulnerability that allows a maliciously crafted image to cause a Denial of Service (DoS) condition. When creating a container from this image, memory exhaustion occurs, leading to an Out Of Memory (OOM) kill of the containerd process. This renders the container runtime API unavailable and can disrupt clients such as the Docker Engine or Kubernetes control-plane components. This issue has been fixed in versions 1.7.33, 2.0.10, 2.1.9, 2.2.5 and 2.3.2.(CVE-2026-47262)
