The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2014-441:02 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-2013-6383     The aac_compat_ioctl function in drivers/scsi/aacraid/linit.c in the Linux kernel before 3.11.8 does not     require the CAP_SYS_RAWIO capability, which allows local users to bypass intended access restrictions via     a crafted ioctl call.
    CVE-2014-0077     drivers/vhost/net.c in the Linux kernel before 3.13.10, when mergeable buffers are disabled, does not     properly validate packet lengths, which allows guest OS users to cause a denial of service (memory     corruption and host OS crash) or possibly gain privileges on the host OS via crafted packets, related to     the handle_rx and get_rx_bufs functions.
    CVE-2014-2523     net/netfilter/nf_conntrack_proto_dccp.c in the Linux kernel through 3.13.6 uses a DCCP header pointer     incorrectly, which allows remote attackers to cause a denial of service (system crash) or possibly execute     arbitrary code via a DCCP packet that triggers a call to the (1) dccp_new, (2) dccp_packet, or (3)     dccp_error function.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Updated kernel packages that fix three security issues and several bugs are now available for Red Hat Enterprise Linux 6.4 Extended Update Support.

The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

* A flaw was found in the way the Linux kernel's netfilter connection tracking implementation for Datagram Congestion Control Protocol (DCCP) packets used the skb_header_pointer() function. A remote attacker could use this flaw to send a specially crafted DCCP packet to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-2523, Important)

* A flaw was found in the way the Linux kernel's Adaptec RAID controller (aacraid) checked permissions of compat IOCTLs. A local attacker could use this flaw to bypass intended security restrictions.
(CVE-2013-6383, Moderate)

* A flaw was found in the way the handle_rx() function handled large network packets when mergeable buffers were disabled. A privileged guest user could use this flaw to crash the host or corrupt QEMU process memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process. (CVE-2014-0077, Moderate)

The CVE-2014-0077 issue was discovered by Michael S. Tsirkin of Red Hat.

This update also fixes several bugs. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section.

All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

The Linux kernel was updated to fix security issues and bugs.

Security issues fixed: CVE-2014-3153: The futex_requeue function in kernel/futex.c in the Linux kernel did not ensure that calls have two different futex addresses, which allowed local users to gain privileges via a crafted FUTEX_REQUEUE command that facilitates unsafe waiter modification.

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 did not check whether a certain length value is sufficiently large, which allowed 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 used the reverse order in a certain subtraction, which allowed 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-2014-0077: drivers/vhost/net.c in the Linux kernel, when mergeable buffers are disabled, did not properly validate packet lengths, which allowed guest OS users to cause a denial of service (memory corruption and host OS crash) or possibly gain privileges on the host OS via crafted packets, related to the handle_rx and get_rx_bufs functions.

CVE-2014-0055: The get_rx_bufs function in drivers/vhost/net.c in the vhost-net subsystem in the Linux kernel package did not properly handle vhost_get_vq_desc errors, which allowed guest OS users to cause a denial of service (host OS crash) via unspecified vectors.

CVE-2014-2678: The rds_iw_laddr_check function in net/rds/iw.c in the Linux kernel allowed 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-2013-7339: The rds_ib_laddr_check function in net/rds/ib.c in the Linux kernel allowed 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-2014-2851: Integer overflow in the ping_init_sock function in net/ipv4/ping.c in the Linux kernel allowed 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.
