CVE-2018-1002100
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.
Does this matter?
Lower severity and a low EPSS score (1.67%). Track it; it rarely justifies an emergency change on its own.
