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.

Description

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.
