### Impact When importing an OCI image, there was no limit on the number of bytes read for certain files. A maliciously crafted image with a large file where a limit was not applied could cause a denial of service. ### Patches This bug has been fixed in containerd 1.6.18 and 1.5.18. 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. ### Credits The containerd project would like to thank David Korczynski and Adam Korczynski of ADA Logics for responsibly disclosing this issue in accordance with the containerd security policy during a security fuzzing audit sponsored by CNCF. ### For more information If you have any questions or comments about this advisory: * Open an issue in containerd * Email us at security@containerd.io To report a security issue in containerd: * Report a new vulnerability * Email us at security@containerd.io
