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.
This bug has been fixed in containerd 1.6.18 and 1.5.18. Users should update to these versions to resolve the issue.
Ensure that only trusted images are used and that only trusted users have permissions to import images.
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.
