Red Hat Security Advisory

Synopsis: Important: ansible and ceph-ansible security, bug fix, and enhancement update
Advisory ID: RHSA-2017:0515-01
Product: Red Hat Storage Console
Advisory URL: https://access.redhat.com/errata/RHSA-2017:0515
Issue date: 2017-03-14
CVE Names: CVE-2016-9587
=====================================================================

1. Summary:

An update for ansible and ceph-ansible is now available for Red Hat Storage
Console 2.

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

2. Relevant releases/architectures:

Red Hat Storage Console Installer 2 - noarch

3. Description:

The ceph-ansible package provides Ansible playbooks for installing,
maintaining, and upgrading Red Hat Ceph Storage.

Ansible is a simple model-driven configuration management, multi-node
deployment, and remote task execution system. Ansible works over SSH and
does not require any software or daemons to be installed on remote nodes.
Extension modules can be written in any language and are transferred to
managed machines automatically.

The following packages have been upgraded to a later upstream version:
ceph-installer (1.2.2), ansible (2.2.1.0), python-passlib (1.6.5),
ceph-ansible (2.1.9). (BZ#1405630)

Security Fix(es):

* An input validation vulnerability was found in Ansible's handling of data
sent from client systems. An attacker with control over a client system
being managed by Ansible and the ability to send facts back to the Ansible
server could use this flaw to execute arbitrary code on the Ansible server
using the Ansible server privileges. (CVE-2016-9587)

Bug Fix(es):

* Previously, the ceph-ansible utility permanently disabled the swap
partition. With this update, ceph-ansible can no longer disable swap.
(BZ#1364167)

* Previously, the ceph-ansible utility did not support adding encrypted OSD
nodes. As a consequence, an attempt to upgrade to a newer, minor, or major
version failed on encrypted OSD nodes. In addition, Ansible returned the
following error message during the disk activation task:

mount: unknown filesystem type 'crypto_LUKS'

With this update, ceph-ansible supports adding encrypted OSD nodes, and
upgrading works as expected. (BZ#1366808)

* Due to a bug in the underlying source code, the ceph-ansible utility in
some cases failed on the copy roundep task. Consequently, the installation
process was unsuccessful. This bug has been fixed, and the installation now
proceeds as expected. (BZ#1382878)

* Previously, installation using the ceph-ansible utility failed on the
"fix partitions gpt header or labels of the journal devices" task in the
ceph-osd role because of an empty variable. The underlying source code has
been modified, and the installation no longer fails in this case.
(BZ#1400967)

* Previously, Red Hat Console Agent setup performed by the ceph-ansible
utility only supported installations by using the Content Delivery Network
(CDN). Installations with an ISO file or local Yum repository failed. With
this update, all installations are successful. (BZ#1403576)

* Previously, the ceph-ansible utility was unable to purge a cluster with
encrypted OSD devices because the underlying ceph-disk utility was unable
to destroy the partition table on an encrypted device by using the
"--zap-disk" option. The underlying source code has been fixed allowing
ceph-disk to use the "--zap-disk" option on encrypted devices. As a result,
ceph-ansible can purge clusters with encrypted OSD devices as expected.
(BZ#1414647)

* Previously, during the creation of Ceph clusters with nodes that use IPv6
addressing, ceph-ansible added the "ms bind ipv6" key to the Ceph
configuration file, but it did not assign any value to it. This behavior
caused an error when parsing the configuration file after the cluster
creation. With this update, the "ms bind ipv6" key is properly set in the
Ceph configuration file allowing for proper configuration file parsing on
clusters that use IPv6 addressing. (BZ#1419814)

Enhancement(s):

* The ceph-ansible utility now supports the client role. This new role
enables you to install Ceph clients by using Ansible and deploy nodes to
run tests against the Ceph cluster. (BZ#1384622)

* The ceph-installer API now supports installation of OSD nodes that have
journals collocated on the same devices. (BZ#1412867)
