  - It was found that FreeIPA 4.2.0 and later could disclose password hashes to users having the 'System: Read
    Stage Users' permission. A remote, authenticated attacker could potentially use this flaw to disclose the
    password hashes belonging to Stage Users. This security issue does not result in disclosure of password
    hashes belonging to active standard users. NOTE: some developers feel that this report is a suggestion for
    a design change to Stage User activation, not a statement of a vulnerability. (CVE-2017-12169)

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