CVE-2022-23648

Name of the Vulnerable Software and Affected Versions containerd versions prior to 1.6.1 containerd versions prior to 1.5.10 containerd versions prior to 1.4.12

Description A bug was found in containerd where containers launched through containerd’s CRI implementation with a specially-crafted image configuration could gain access to read-only copies of arbitrary files and directories on the host. This may bypass any policy-based enforcement on container setup, including a Kubernetes Pod Security Policy, and expose potentially sensitive information. Kubernetes and crictl can both be configured to use containerd’s CRI implementation.

Recommendations Update to containerd version 1.6.1 to resolve the issue. Update to containerd version 1.5.10 to resolve the issue. Update to containerd version 1.4.12 to resolve the issue. As a temporary workaround, ensure that only trusted images are used.
