Allocation of Resources Without Limits or Throttling


Severity Medium
Score 5.5/10


Containerd is an open source container runtime. In versions through 1.5.17 and 1.6.0 through 1.6.17, and v1.7.0-beta.1 through v1.7.0-beta.3 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. Users should update to these versions to resolve the issue. As a workaround, ensure that only trusted images are used and that only trusted users have permission to import images.
