"The remote MiracleLinux 4 host has a package installed that is affected by multiple vulnerabilities as referenced in the
AXSA:2014-027:01 advisory.

    Sudo (superuser do) allows a system administrator to give certain users (or groups of users) the ability
    to run some (or all) commands as root while logging all commands and arguments. Sudo operates on a per-
    command basis. It is not a replacement for the shell. Features include: the ability to restrict what
    commands a user may run on a per-host basis, copious logging of each command (providing a clear audit
    trail of who did what), a configurable timeout of the sudo command, and the ability to use the same
    configuration file (sudoers) on many different machines.
    Security issues fixed with this release:
     CVE-2013-1775
    sudo 1.6.0 through 1.7.10p6 and sudo 1.8.0 through 1.8.6p6 allows local users or physically-proximate
    attackers to bypass intended time restrictions and retain privileges without re-authenticating by setting
    the system clock and sudo user timestamp to the epoch.
     CVE-2013-2776
    udo 1.3.5 through 1.7.10p5 and 1.8.0 through 1.8.6p6, when running on systems without /proc or the sysctl
    function with the tty_tickets option enabled, does not properly validate the controlling terminal device,
    which allows local users with sudo permissions to hijack the authorization of another terminal via vectors
    related to connecting to a standard input, output, and error file descriptors of another terminal. NOTE:
    this is one of three closely-related vulnerabilities that were originally assigned CVE-2013-1776, but they
    have been SPLIT because of different affected versions.
     CVE-2013-2777
    sudo before 1.7.10p5 and 1.8.x before 1.8.6p6, when the tty_tickets option is enabled, does not properly
    validate the controlling terminal device, which allows local users with sudo permissions to hijack the
    authorization of another terminal via vectors related to a session without a controlling terminal device
    and connecting to a standard input, output, and error file descriptors of another terminal. NOTE: this is
    one of three closely-related vulnerabilities that were originally assigned CVE-2013-1776, but they have
    been SPLIT because of different affected versions.
    Fixed bugs:
     sudo now supports netgroup filtering for sources from the SSSD. Previously, SSSD rules applied to all
    users, even those not part of the specified netgroup. They now only apply to users belonging to the
    specified netgroup.
     Previously, if both the soft (current) and hard (maximum) values of RLIMIT_NPROC were not limited, sudo
    would reset them to the parent's value of these limits. This has been fixed and RLIMIT_NPROC can now
    really be set to unlimited.
     Restored the previous behaviour of sudo and the name of the user running the sudo command is now logged
    again, instead of root.
     Fixed an error in a loop condition that sometimes triggered a buffer overflow.
    Enhancements:
     sudo now sends debug messages about netgroup matching to the debug log.
     sudo now accepts the ipa_hostname value from the /etc/sssd/sssd.conf configuration file when matching
    netgroups.
