  - containerd is a container runtime available as a daemon for Linux and Windows. A bug was found in
    containerd prior to versions 1.6.1, 1.5.10, and 1.14.12 where containers launched through containerd's CRI
    implementation on Linux 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. This bug has been
    fixed in containerd 1.6.1, 1.5.10, and 1.4.12. Users should update to these versions to resolve the issue.
    (CVE-2022-23648)
