During the `PullImage` operation, the recursive traversal and processing of child descriptors lack sufficient depth and breadth limits, and fail to adequately deduplicate identical descriptors. This unbounded traversal leads to excessive resource allocation.\n\nConsequently, pulling a malicious image reference can result in prolonged stalls during container creation and significant resource pressure on the host system. This issue occurs entirely during the image pull phase, prior to any container execution.\n\n### Patches\n\nThis bug has been fixed in containerd 2.4.1, 2.3.6, 2.2.9, 2.0.13, and 1.7.36. Users should update to these versions to resolve the issue.\n\n### Workarounds\n\nThere are no known workarounds for this issue. Users are advised to only pull trusted images from known registries until the patch can be applied.\n\n### Credits\n\nThe containerd project would like to thank Jakub Ciolek at ElevenLabs and @jlgore who independently discovered and responsibly disclosed this issue in accordance with the [containerd security policy](https://github.com/containerd/project/blob/main/SECURITY.md).\n\n### For more
