"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied
patch available.

  - A flaw was found in the use of insufficiently random values in Ansible. Two random password lookups of the
    same length generate the equal value as the template caching action for the same file since no re-
    evaluation happens. The highest threat from this vulnerability would be that all passwords are exposed at
    once for the file. This flaw affects Ansible Engine versions before 2.9.6. (CVE-2020-10729)

Note that Nessus relies on the presence of the package as reported by the vendor.");
