1. Summary:

An update for ansible is now available for Red Hat Enterprise Linux 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.

Red Hat Enterprise Linux 7 Extras - 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 ansible packages have been upgraded to upstream version 2.4.0, which
provides a number of bug fixes and enhancements over the previous version.
For more information, please see the Ansible 2.4 Porting Guide linked in
the References section. (BZ#1492477)

Security Fix(es):

* A flaw was found in the way Ansible passed certain parameters to the
jenkins_plugin module. A remote attacker could use this flaw to expose
sensitive information from a remote host's logs. This flaw was fixed by not
allowing passwords to be specified in the "params" argument, and noting
this in the module documentation. (CVE-2017-7550)

Red Hat would like to thank Stefano Mazzucco (Kirontech) for reporting this

Bug Fix(es):

* A bug in the SELinux module, which caused a corruption of the SELinux
configuration file, has been fixed.

* Previously, some of the functionality of Ansible (the json_query filter)
was unavailable, because the dependency on the python2-jmespath package was
missing. Now, the missing dependency has been added. (BZ#1484910)
