"The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2014-490:04 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-2012-6647
    The futex_wait_requeue_pi function in kernel/futex.c in the Linux kernel before 3.5.1 does not ensure that
    calls have two different futex addresses, which allows local users to cause a denial of service (NULL
    pointer dereference and system crash) or possibly have unspecified other impact via a crafted
    FUTEX_WAIT_REQUEUE_PI command.
    CVE-2013-7339
    The rds_ib_laddr_check function in net/rds/ib.c in the Linux kernel before 3.12.8 allows local users to
    cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other
    impact via a bind system call for an RDS socket on a system that lacks RDS transports.
    CVE-2014-2672
    Race condition in the ath_tx_aggr_sleep function in drivers/net/wireless/ath/ath9k/xmit.c in the Linux
    kernel before 3.13.7 allows remote attackers to cause a denial of service (system crash) via a large
    amount of network traffic that triggers certain list deletions.
    CVE-2014-2678
    The rds_iw_laddr_check function in net/rds/iw.c in the Linux kernel through 3.14 allows local users to
    cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other
    impact via a bind system call for an RDS socket on a system that lacks RDS transports.
    CVE-2014-2706
    Race condition in the mac80211 subsystem in the Linux kernel before 3.13.7 allows remote attackers to
    cause a denial of service (system crash) via network traffic that improperly interacts with the
    WLAN_STA_PS_STA state (aka power-save mode), related to sta_info.c and tx.c.
    CVE-2014-2851
    Integer overflow in the ping_init_sock function in net/ipv4/ping.c in the Linux kernel through 3.14.1
    allows local users to cause a denial of service (use-after-free and system crash) or possibly gain
    privileges via a crafted application that leverages an improperly managed reference counter.
    CVE-2014-3144
    The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST extension implementations in the sk_run_filter
    function in net/core/filter.c in the Linux kernel through 3.14.3 do not check whether a certain length
    value is sufficiently large, which allows local users to cause a denial of service (integer underflow and
    system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr and
    __skb_get_nlattr_nest functions before the vulnerability was announced.
    CVE-2014-3145
    The BPF_S_ANC_NLATTR_NEST extension implementation in the sk_run_filter function in net/core/filter.c in
    the Linux kernel through 3.14.3 uses the reverse order in a certain subtraction, which allows local users
    to cause a denial of service (over-read and system crash) via crafted BPF instructions. NOTE: the affected
    code was moved to the __skb_get_nlattr_nest function before the vulnerability was announced.
    CVE-2014-4699
    The Linux kernel before 3.15.4 on Intel processors does not properly restrict use of a non-canonical value
    for the saved RIP address in the case of a system call that does not use IRET, which allows local users to
    leverage a race condition and gain privileges, or cause a denial of service (double fault), via a crafted
    application that makes ptrace and fork system calls.
    CVE-2014-4943
    The PPPoL2TP feature in net/l2tp/l2tp_ppp.c in the Linux kernel through 3.15.6 allows local users to gain
    privileges by leveraging data-structure differences between an l2tp socket and an inet socket.
