The Kubernetes kube-apiserver mistakenly allows access to a cluster-scoped custom resource if the request is made as if the resource were namespaced. Authorizations for the resource accessed in this manner are enforced using roles and role bindings within the namespace, meaning that a user with access only to a resource in one namespace could create, view update or delete the cluster-scoped resource (according to their namespace role privileges). Kubernetes affected versions include versions prior to 1.13.9, versions prior to 1.14.5, versions prior to 1.15.2, and versions 1.7, 1.8, 1.9, 1.10, 1.11, 1.12.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

    is made as if the resource were namespaced. Authorizations for the resource accessed in this manner are
    enforced using roles and role bindings within the namespace, meaning that a user with access only to a

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - The Kubernetes kube-apiserver mistakenly allows access to a cluster-scoped custom resource if the request
    is made as if the resource were namespaced. Authorizations for the resource accessed in this manner are
    enforced using roles and role bindings within the namespace, meaning that a user with access only to a

  - The kubectl cp command allows copying files between containers and the user machine. To copy files from a
    container, Kubernetes runs tar inside the container to create a tar archive, copies it over the network,
    and kubectl unpacks it on the user’s machine. If the tar binary in the container is malicious, it could
    run any code and output unexpected, malicious results. An attacker could use this to write files to any
    path on the user’s machine when kubectl cp is called, limited only by the system permissions of the local
    user. Kubernetes affected versions include versions prior to 1.13.9, versions prior to 1.14.5, versions
    prior to 1.15.2, and versions 1.1, 1.2, 1.4, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 1.10, 1.11, 1.12.
