Description

An updated ceph-deploy package that fixes two security issues is now available for Red Hat Ceph Storage.

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.

Red Hat Ceph Storage is a massively scalable, open, software-defined storage platform that combines the most stable version of Ceph with a Ceph management platform, deployment tools, and support services.

It was discovered that ceph-deploy, a utility for deploying Red Hat Ceph Storage, would create the keyring file with world readable permissions, which could possibly allow a local user to obtain authentication credentials from the keyring file. (CVE-2015-3010, CVE-2015-4053)

All ceph-deploy users are advised to upgrade to this updated package, which contains backported patches to correct these issues.
