"The remote MiracleLinux 4 host has packages installed that are affected by a vulnerability as referenced in the
AXSA:2011-152:01 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-2011-1011
    The seunshare_mount function in sandbox/seunshare.c in seunshare in certain Asianux packages of
    policycoreutils 2.0.83 and earlier in Asianux Server 4 and earlier, mounts a new directory on top of /tmp
    without assigning root ownership and the sticky bit to this new directory, which allows local users to
    replace or delete arbitrary /tmp files, and consequently cause a denial of service or possibly gain
    privileges, by running a setuid application that relies on /tmp, as demonstrated by the ksu application.

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
number.");
