CVE-2020-8557

Priority
Description
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 kubelet is not
included by the kubelet eviction manager when calculating ephemeral storage
usage by a pod. If a pod writes a large amount of data to the /etc/hosts
file, it could fill the storage space of the node and cause the node to
fail.
Notes
leosilvakubernates is in fact a kubernetes installer
that calls snap, not the package it self.
