## Description

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 1.12.9,
versions prior to 1.13.6, versions prior to 1.14.2, and versions 1.1, 1.2,
1.4, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 1.10, 1.11.
