"The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2016-714:08 advisory.

    The kernel package contains the Linux kernel (vmlinuz), the core of any
    Linux operating system.  The kernel handles the basic functions
    of the operating system: memory allocation, process allocation, device
    input and output, etc.
    Security issues fixed with this release:
    CVE-2016-4470
    The key_reject_and_link function in security/keys/key.c in the Linux
    kernel through 4.6.3 does not ensure that a certain data structure is
    initialized, which allows local users to cause a denial of service
    (system crash) via vectors involving a crafted keyctl request2
    command.
    CVE-2016-5829
    Multiple heap-based buffer overflows in the hiddev_ioctl_usage
    function in drivers/hid/usbhid/hiddev.c in the Linux kernel through
    4.6.3 allow local users to cause a denial of service or possibly have
    unspecified other impact via a crafted (1) HIDIOCGUSAGES or (2)
    HIDIOCSUSAGES ioctl call.
    Fixed bugs:
    * Previously, when two NFS shares with different security settings were mounted, the I/O operations to the
    kerberos-authenticated mount caused the RPC_CRED_KEY_EXPIRE_SOON parameter to be set, but the parameter
    was not unset when performing the I/O operations on the sec=sys mount. Consequently, writes to both NFS
    shares had the same parameters, regardless of their security settings. This update fixes this problem by
    moving the NO_CRKEY_TIMEOUT parameter to the auth-
