"An update for the container-tools:rhel8 module is now available for
Red Hat Enterprise Linux 8.

Red Hat Product Security has rated this update as having a security
impact of Important. 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 container-tools module contains tools for working with containers,
