Red Hat Security Advisory
Synopsis: Moderate: ansible security and bug fix update
Advisory ID: RHSA-2018:2022-01
Product: Red Hat Ansible Engine
Advisory URL: https://access.redhat.com/errata/RHSA-2018:2022
Issue date: 2018-06-26
CVE Names: CVE-2018-10855
=====================================================================
1. Summary:
An update for ansible is now available for Red Hat Ansible Engine 2.4 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 2.4 for RHEL 7 Server - 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 (2.4.5)
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):
* Fixed win_copy to preserve the global Ansible local tmp path instead of
deleting it when dealing with multiple files
(https://github.com/ansible/ansible/pull/37964)
* Fixed Windows setup.ps1 for slow performance in large domain environments
(https://github.com/ansible/ansible/pull/38646)
* Fixed eos_logging idempotency issue when trying to set both logging
destination & facility
(https://github.com/ansible/ansible/pull/40604)
* Fixed ios_logging idempotency issue when trying to set both logging
destination & facility
(https://github.com/ansible/ansible/pull/41076)
