CVE-2022-31030

Name of the Vulnerable Software and Affected Versions containerd versions prior to 1.5.13 containerd versions prior to 1.6.6

Description A bug was found in the containerd's CRI implementation where programs inside a container can cause the containerd daemon to consume memory without bound during invocation of the ExecSync API. This can cause containerd to consume all available memory on the computer, denying service to other legitimate workloads. Kubernetes and crictl can both be configured to use containerd's CRI implementation; ExecSync may be used when running probes or when executing processes via an "exec" facility.

Recommendations For versions prior to 1.5.13, update to version 1.5.13 to resolve the issue. For versions prior to 1.6.6, update to version 1.6.6 to resolve the issue. As a temporary workaround, ensure that only trusted images and commands are used. Consider restricting the use of the ExecSync API until the issue is resolved.
