RHEL 7 : ansible (RHSA-2017:2966)

critical Nessus Plugin ID 104005

Language:

Synopsis

The remote Red Hat host is missing a security update.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2017:2966 advisory.

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 issue.

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)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected ansible and / or ansible-doc packages.
