                   Red Hat Security Advisory

Synopsis:          Important: ansible and gdeploy security and bug fix update
Advisory ID:       RHSA-2017:0260-01
Product:           Red Hat Gluster Storage
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2017-0260.html
Issue date:        2017-02-07
CVE Names:         CVE-2016-9587 
=====================================================================

1. Summary:

An update for ansible and gdeploy is now available for Red Hat Gluster
Storage 3.1 for RHEL 7.

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 Gluster Storage Server 3.1 on RHEL-7 - noarch

3. Description:

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 gdeploy package provides Ansible modules to setup and configure
GluterFS.

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, if SELinux Policy Management tool was not installed, gdeploy
did not display any error. Hence, the SELinux context was not being set.
With this update, gdeploy throws error if SELinux Policy Management tool is
not installed on the machine. (BZ#1340038)

* This update introduces the Slice Unit configuration feature for the
glusterfs services to organize a hierarchy for barriering the processes
within a specific memory, cpu limits. This feature ensures that the Red Hat
Gluster Storage's systemd unit(s) starts within the specified Slice. To
configure Slice, add the following parameter to the configuration file:
slice_setup=yes (BZ#1349790)
