The remote Redhat Enterprise Linux 7 / 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:0218 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 (2.9.4)
Bug Fix(es):
* CVE-2019-14904 Ansible: vulnerability in solaris_zone module via crafted solaris zone
* CVE-2019-14905 Ansible: malicious code could craft filename in nxos_file_copy module
See:
https://github.com/ansible/ansible/blob/v2.9.4/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.
