Summary

containerd overlaybd through 1.0.18 has a do_load_index (LSMT index loading) integer overflow (and resultant out-of-bounds heap access) for index_bytes, if an untrusted overlaybd blob from a registry is used in a scenario with multiple overlaybd-backed containers.

Risk Assessment

The risk includes potential container crashes or memory safety violations, potentially leading to unauthorized access or denial of service.

Recommendation

Upgrade containerd overlaybd to a version later than 1.0.18 and avoid using untrusted blobs from registries in multi-container environments.
