RHSA-2015_0776

Vulnerability from csaf_redhat - Published: 2015-04-02 19:31 - Updated: 2024-11-22 09:03
Summary
Red Hat Security Advisory: docker security update

Notes

Topic
Updated docker packages that fix one security issue are now available for Red Hat Enterprise Linux 7 Extras. Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
Details
Docker is a service providing container management on Linux. It was found that the fix for the CVE-2014-5277 issue was incomplete: the docker client could under certain circumstances erroneously fall back to HTTP when an HTTPS connection to a registry failed. This could allow a man-in-the-middle attacker to obtain authentication and image data from traffic sent from a client to the registry. (CVE-2015-1843) Red Hat would like to thank Eric Windisch of Docker Inc. for reporting this issue. All docker users are advised to upgrade to these updated packages, which correct this issue.
