RHEL 7 / 8 : Ansible security update (2.9.18) (Moderate) (RHSA-2021:0663)

high Nessus Plugin ID 146820

Synopsis

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

Description

The remote Redhat Enterprise Linux 7 / 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:0663 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 following packages have been upgraded to a newer upstream version:
ansible (2.9.18)

Bug Fix(es):
* CVE-2021-20178 ansible: user data leak in snmp_facts module
* CVE-2021-20180 ansible module: bitbucket_pipeline_variable exposes secured values
* CVE-2021-20191 ansible: multiple collections exposes secured values
* CVE-2021-20228 ansible: basic.py no_log with fallback option

See:
https://github.com/ansible/ansible/blob/v2.9.18/changelogs/CHANGELOG-v2.9.rst for details on bug fixes in this release.

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-2021:0663.
