1. Summary:

An update for ansible is now available for Red Hat OpenStack Platform 10.0

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 OpenStack Platform 10.0 - 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.

Security Fix(es):

* ansible: Failed tasks do not honour no_log option allowing for secrets to
be disclosed in logs (CVE-2018-10855)

* ansible: Inventory variables are loaded from current working directory
when running ad-hoc command that can lead to code execution

* ansible: ansible.cfg is being read from current working directory
allowing possible code execution (CVE-2018-10875)

For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
the References section.
