Platform 4.3.

Red Hat Product Security has rated this update as having a security
impact of Low. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link (s) in the References section.

The podman tool manages Pods, container images, and containers. It is
part of the libpod library, which is for applications that use
container Pods. Container Pods is a concept in Kubernetes.

Security Fix(es) :

* podman: incorrectly allowed existing files in volumes to be
overwritten by a container when it was created (CVE-2020-1726)

For more details about the security issue(s), including the impact, a
CVSS score, acknowledgments, and other related information, refer to
