The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4792-1 advisory.

    It was discovered that FreeIPA incorrectly handled certificates. An attacker could possibly use this issue     to cause a denial of service by revoking arbitrary certificates This issue only affected Ubuntu 16.04 ESM.
    (CVE-2016-5404)

    It was discovered that FreeIPA incorrectly handled authentication attempts. An attacker could possibly use     this issue to cause a denial of service. (CVE-2016-7030)

    It was discovered that FreeIPA incorrectly handled user's permissions. An authenticated attacker could     possibly use this issue to modify other user's profiles or other unspecified impact. This issue only     affected Ubuntu 16.04 ESM. (CVE-2016-9575)

The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2017-1217:01 advisory.

    IPA is an integrated solution to provide centrally managed Identity (users,     hosts, services), Authentication (SSO, 2FA), and Authorization     (host access control, SELinux user roles, services). The solution provides     features for further integration with Linux based clients (SUDO, automount)     and integration with Active Directory based infrastructures (Trusts).
    Security issues fixed with this release:
    CVE-2016-7030
    ** RESERVED **     This candidate has been reserved by an organization or individual that     will use it when announcing a new security problem.  When the     candidate has been publicized, the details for this candidate will be     provided.

An update for ipa is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Red Hat Identity Management (IdM) is a centralized authentication, identity management, and authorization solution for both traditional and cloud-based enterprise environments.

Security Fix(es) :

* It was discovered that the default IdM password policies that lock out accounts after a certain number of failed login attempts were also applied to host and service accounts. A remote unauthenticated user could use this flaw to cause a denial of service attack against kerberized services. (CVE-2016-7030)

* It was found that IdM's certprofile-mod command did not properly check the user's permissions while modifying certificate profiles. An authenticated, unprivileged attacker could use this flaw to modify profiles to issue certificates with arbitrary naming or key usage information and subsequently use such certificates for other attacks.
(CVE-2016-9575)

The CVE-2016-7030 issue was discovered by Petr Spacek (Red Hat) and the CVE-2016-9575 issue was discovered by Liam Campbell (Red Hat).

According to the versions of the ipa packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - It was discovered that the default IdM password     policies that lock out accounts after a certain number     of failed login attempts were also applied to host and     service accounts. A remote unauthenticated user could     use this flaw to cause a denial of service attack     against kerberized services. (CVE-2016-7030)

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

  - FreeIPA uses a default password policy that locks an account after 5 unsuccessful authentication attempts,     which allows remote attackers to cause a denial of service by locking out the account in which system     services run on. (CVE-2016-7030)

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