"The remote MiracleLinux 4 host has packages installed that are affected by a vulnerability as referenced in the
AXSA:2016-915:02 advisory.

    Security-enhanced Linux is a feature of the Linux kernel and a number
    of utilities with enhanced security functionality designed to add
    mandatory access controls to Linux.  The Security-enhanced Linux
    kernel contains new architectural components originally developed to
    improve the security of the Flask operating system. These
    architectural components provide general support for the enforcement
    of many kinds of mandatory access control policies, including those
    based on the concepts of Type Enforcement, Role-based Access
    Control, and Multi-level Security.
    policycoreutils contains the policy core utilities that are required
    for basic operation of a SELinux system.  These utilities include
    load_policy to load policies, setfiles to label filesystems, newrole
    to switch roles, and run_init to run /etc/init.d scripts in the proper
    context.
    Security issues fixed with this release:
    CVE-2016-7545
    ** 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.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
