Summary
kata-containers security update
Details

This is core component of Kata Container, to make it work, you need a isulad/docker engine.

Security Fix(es):

An improper file permissions vulnerability affects Kata Containers prior to 1.11.5. When using a Kubernetes hostPath volume and mounting either a file or directory into a container as readonly, the file/directory is mounted as readOnly inside the container, but is still writable inside the guest. For a container breakout situation, a malicious guest can potentially modify or delete files/directories expected to be read-only.(CVE-2020-28914)

Severity
