An update for docker is now available for Red Hat Enterprise Linux 7 Extras.

Red Hat Product Security has rated this update as having a security impact of Moderate. 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.

Description

Docker is an open-source engine that automates the deployment of any application as a lightweight, portable, self-sufficient container that will run virtually anywhere.

This issue was discovered by Mrunal Patel (Red Hat).

Bug Fix(es):

  • This update also provides various bug fixes and enhancements. Users are advised to upgrade to these updated packages.
