The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2021:2180 advisory.
The ovirt-engine package provides the Red Hat Virtualization Manager, a centralized management platform that allows system administrators to view and manage virtual machines. The Manager provides a comprehensive range of features including search capabilities, resource management, live migrations, and virtual infrastructure provisioning.
Security Fix(es):
* ansible: user data leak in snmp_facts module (CVE-2021-20178)
* ansible module: bitbucket_pipeline_variable exposes secured values (CVE-2021-20180)
* ansible: multiple modules expose secured values (CVE-2021-20191)
* ansible: basic.py no_log with fallback option (CVE-2021-20228)
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.
Bug Fix(es):
* Red Hat Virtualization 4.4.6 now requires Ansible 2.9.18 (BZ#1933672)
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.
