high Nessus Plugin ID 135915

Language:

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 a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2020:1543 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 (2.8.11)

Bug Fix(es):
* CVE-2020-10684 Ansible: code injection when using ansible_facts as a subkey
* CVE-2020-10685 Ansible: modules which use files encrypted with vault are not properly cleaned up
* CVE-2020-1733 ansible: insecure temporary directory when running become_user from become directive
* CVE-2020-1735 ansible: path injection on dest parameter in fetch module
* CVE-2020-1737 ansible: Extract-Zip function in win_unzip module does not check extracted path
* CVE-2020-1739 ansible: svn module leaks password when specified as a parameter
* CVE-2020-1740 ansible: secrets readable after ansible-vault edit
* CVE-2020-1746 ansible: Information disclosure issue in ldap_attr and ldap_entry modules

See:
https://github.com/ansible/ansible/blob/v2.8.11/changelogs/CHANGELOG-v2.8.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-2020:1543.
