"An update for Ansible is now available for Ansible Engine 2.9.

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.

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: Splunk and Sumologic callback plugins leak sensitive data in
logs (CVE-2019-14864)

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

The following packages have been upgraded to a newer upstream version:
ansible (2.9.1)

Bug Fix(es) :

See:
https://github.com/ansible/ansible/blob/v2.9.1/changelogs/CHANGELOG-v2
.9.rst for details on bug fixes in this release.");
