Descriptions

In Kubernetes versions 1.5.x, 1.6.x, 1.7.x, 1.8.x, and prior to version 1.9.6, the kubectl cp command insecurely handles tar data returned from the container, and can be caused to overwrite arbitrary local files.

En las versiones 1.5.x, 1.6.x, 1.7.x, 1.8.x y anteriores a la versión 1.9.6 de Kubernetes, el comando kubectl cp gestiona de forma insegura los datos tar devueltos del contenedor, lo que puede sobrescribir archivos locales arbitrarios.
