The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2014-454:03 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-2013-6378     The lbs_debugfs_write function in drivers/net/wireless/libertas/debugfs.c in the Linux kernel through     3.12.1 allows local users to cause a denial of service (OOPS) by leveraging root privileges for a zero-     length write operation.
    CVE-2014-0203     The __do_follow_link function in fs/namei.c in the Linux kernel before 2.6.33 does not properly handle the     last pathname component during use of certain filesystems, which allows local users to cause a denial of     service (incorrect free operations and system crash) via an open system call.
    CVE-2014-1737     The raw_cmd_copyin function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly     handle error conditions during processing of an FDRAWCMD ioctl call, which allows local users to trigger     kfree operations and gain privileges by leveraging write access to a /dev/fd device.
    CVE-2014-1738     The raw_cmd_copyout function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not     properly restrict access to certain pointers during processing of an FDRAWCMD ioctl call, which allows     local users to obtain sensitive information from kernel heap memory by leveraging write access to a     /dev/fd device.
    CVE-2014-1874     The security_context_to_sid_core function in security/selinux/ss/services.c in the Linux kernel before     3.13.4 allows local users to cause a denial of service (system crash) by leveraging the CAP_MAC_ADMIN     capability to set a zero-length security context.
    CVE-2014-2039     arch/s390/kernel/head64.S in the Linux kernel before 3.13.5 on the s390 platform does not properly handle     attempted use of the linkage stack, which allows local users to cause a denial of service (system crash)     by executing a crafted instruction     CVE-2014-3153     The futex_requeue function in kernel/futex.c in the Linux kernel through 3.14.5 does not ensure that calls     have two different futex addresses, which allows local users to gain privileges via a crafted     FUTEX_REQUEUE command that facilitates unsafe waiter modification.

* A flaw was found in the way the Linux kernel's futex subsystem handled the requeuing of certain Priority Inheritance (PI) futexes. A local, unprivileged user could use this flaw to escalate their privileges on the system. (CVE-2014-3153, Important)

* A flaw was found in the way the Linux kernel's floppy driver handled user space provided data in certain error code paths while processing FDRAWCMD IOCTL commands. A local user with write access to /dev/fdX could use this flaw to free (using the kfree() function) arbitrary kernel memory. (CVE-2014-1737, Important)

* It was found that the Linux kernel's floppy driver leaked internal kernel memory addresses to user space during the processing of the FDRAWCMD IOCTL command. A local user with write access to /dev/fdX could use this flaw to obtain information about the kernel heap arrangement. (CVE-2014-1738, Low)

Note: A local user with write access to /dev/fdX could use these two flaws (CVE-2014-1737 in combination with CVE-2014-1738) to escalate their privileges on the system.

* It was discovered that the proc_ns_follow_link() function did not properly return the LAST_BIND value in the last pathname component as is expected for procfs symbolic links, which could lead to excessive freeing of memory and consequent slab corruption. A local, unprivileged user could use this flaw to crash the system.
(CVE-2014-0203, Moderate)

* A flaw was found in the way the Linux kernel handled exceptions when user-space applications attempted to use the linkage stack. On IBM S/390 systems, a local, unprivileged user could use this flaw to crash the system. (CVE-2014-2039, Moderate)

* An invalid pointer dereference flaw was found in the Marvell 8xxx Libertas WLAN (libertas) driver in the Linux kernel. A local user able to write to a file that is provided by the libertas driver and located on the debug file system (debugfs) could use this flaw to crash the system. Note: The debugfs file system must be mounted locally to exploit this issue. It is not mounted by default. (CVE-2013-6378, Low)

* A denial of service flaw was discovered in the way the Linux kernel's SELinux implementation handled files with an empty SELinux security context. A local user who has the CAP_MAC_ADMIN capability could use this flaw to crash the system. (CVE-2014-1874, Low)
