Описание
containerd image-triggered runtime DoS via unbounded group parsing
Impact
A vulnerability in containerd 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.
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 and that only trusted users have permissions to import images or schedule pods.
