Product: Red Hat Ceph Storage
Advisory URL: https://access.redhat.com/errata/RHSA-2015:1579

=====================================================================
1. Summary:
An updated ceph-deploy package that fixes two security issues is now
available in Red Hat Ceph Storage for Ubuntu 12.04 and Ubuntu 14.04.
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.
2. 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)
ceph has been upgraded from v0.80.8.1 to v0.80.8.2. This upgrade fixes the
following bugs:
- - - .rgw pool contains extra objects (rhbz #1212524)
- - - rgw bucket/object owner override when setting acls (rhbz #1214051)
- - - librbd: aio calls may block (rhbz #1225172)
ice_setup has been upgraded from v0.3.0-2 to v0.3.2. This upgrade fixes a
bug where ice_setup would crash if the "setuptools" Python package was not
already installed on the Calamari admin node. (rhbz #1212045)
All ceph-deploy users are advised to upgrade to this updated package, which
contains backported patches to correct these issues.
3. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
Refer to Knowledge Base article https://access.redhat.com/articles/1554343
for download link and signing information.
