Product:           Red Hat Ansible Engine
Advisory URL:      https://access.redhat.com/errata/RHSA-2018:1948

=====================================================================

1. Summary:

An update for ansible is now available for Red Hat Ansible Engine 2 for
RHEL 7.

Red Hat Product Security has rated this update as having a security impact
of Moderate. 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 Ansible Engine 2 for 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 following packages have been upgraded to a newer upstream version:
ansible (2.5.5)

Security fix(es):

* ansible: Ansible through version 2.5 does not properly honour the no_log
option with failed task iterations. When a list of secret items is supplied
to a task and a task iteration fails, secrets can be disclosed in logs
despite the no_log option being enabled. (CVE-2018-10855)

Red Hat would like to thank Tobias Henkel (BMW Car IT GmbH) for
reporting these issues.

Bug Fix(es):

* Changed the admin_users config option to not include "admin" by
 default
as admin is frequently used for a non-privileged account
(https://github.com/ansible/ansible/pull/41164)

* aws_s3 - add async support to the action plugin
(https://github.com/ansible/ansible/pull/40826)

* aws_s3 - fix decrypting vault files
(https://github.com/ansible/ansible/pull/39634)

* ec2_ami - cast the device_mapping volume size to an int
(https://github.com/ansible/ansible/pull/40938)

* eos_logging - fix idempotency issues
(https://github.com/ansible/ansible/pull/40604)

* cache plugins - a cache timeout of 0 means the cache will not expire.

* ios_logging - fix idempotency issues
(https://github.com/ansible/ansible/pull/41029)

* ios/nxos/eos_config - don't retrieve config in running_config when config
is provided for diff (https://github.com/ansible/ansible/pull/41400)

* nxos_banner - fix multiline banner issue
(https://github.com/ansible/ansible/pull/41026).

* nxos terminal plugin - fix output truncation
(https://github.com/ansible/ansible/pull/40960)
