Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- The Kubernetes kubelet component in versions 1.1-1.16.12, 1.17.0-1.17.8 and 1.18.0-1.18.5 do not account
for disk usage by a pod which writes to its own /etc/hosts file. The /etc/hosts file mounted in a pod by
