RHEL 7 : ansible (RHSA-2019:0054)

high Nessus Plugin ID 194068

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for ansible.

Description

The remote Redhat Enterprise Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2019:0054 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.

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 (CVE-2018-10874)

* 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.

Red Hat would like to thank Tobias Henkel (BMW Car IT GmbH) for reporting CVE-2018-10855 and Michael Scherer (OSAS) for reporting CVE-2018-10874. The CVE-2018-10875 issue was discovered by Brian Coca (Red Hat).

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

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

Solution

Update the RHEL ansible package based on the guidance in RHSA-2019:0054.
