The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2014:0981 advisory.

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

    * A use-after-free flaw was found in the way the ping_init_sock() function     of the Linux kernel handled the group_info reference counter. A local,     unprivileged user could use this flaw to crash the system or, potentially,     escalate their privileges on the system. (CVE-2014-2851, Important)

    * A NULL pointer dereference flaw was found in the way the     futex_wait_requeue_pi() function of the Linux kernel's futex subsystem     handled the requeuing of certain Priority Inheritance (PI) futexes.
    A local, unprivileged user could use this flaw to crash the system.
    (CVE-2012-6647, Moderate)

    * A NULL pointer dereference flaw was found in the rds_ib_laddr_check()     function in the Linux kernel's implementation of Reliable Datagram Sockets     (RDS). A local, unprivileged user could use this flaw to crash the system.
    (CVE-2013-7339, Moderate)

    * It was found that a remote attacker could use a race condition flaw in     the ath_tx_aggr_sleep() function to crash the system by creating large     network traffic on the system's Atheros 9k wireless network adapter.
    (CVE-2014-2672, Moderate)

    * A NULL pointer dereference flaw was found in the rds_iw_laddr_check()     function in the Linux kernel's implementation of Reliable Datagram Sockets     (RDS). A local, unprivileged user could use this flaw to crash the system.
    (CVE-2014-2678, Moderate)

    * A race condition flaw was found in the way the Linux kernel's mac80211     subsystem implementation handled synchronization between TX and STA wake-up     code paths. A remote attacker could use this flaw to crash the system.
    (CVE-2014-2706, Moderate)

    * An out-of-bounds memory access flaw was found in the Netlink Attribute     extension of the Berkeley Packet Filter (BPF) interpreter functionality in     the Linux kernel's networking implementation. A local, unprivileged user     could use this flaw to crash the system or leak kernel memory to user space     via a specially crafted socket filter. (CVE-2014-3144, CVE-2014-3145,     Moderate)

    This update also fixes several bugs and adds one enhancement.
    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 and add this     enhancement. The system must be rebooted for this update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux 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 multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6.4 Extended Update Support.

Red Hat Product Security 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.

This update also fixes the following bugs :

* The Completely Fair Scheduler (CFS) did not verify whether the CFS period timer is running while throttling tasks on the CFS run queue.
Therefore under certain circumstances, the CFS run queue became stuck because the CFS period timer was inactive and could not be restarted.
To fix this problem, the CFS now restarts the CFS period timer inside the throttling function if it is inactive. (BZ#1120666)

* A previous change to the SCSI code fixed a race condition that could occur when removing a SCSI device. However, that change caused performance degradation because it used a certain function from the block layer code that was returning different values compared with later versions of the kernel. This update alters the SCSI code to properly utilize the values returned by the block layer code.
(BZ#1117581)

* If a statically defined gateway became unreachable and its corresponding neighbor entry entered a FAILED state, the gateway stayed in the FAILED state even after it became reachable again. This prevented routing of the traffic through that gateway. This update allows probing such a gateway automatically and routing the traffic through the gateway again once it becomes reachable. (BZ#1115262)

* A miscalculation in the 'radix_tree' swap encoding corrupted swap area indexes bigger than 8 by truncating lower bits of swap entries.
Consequently, systems with more than 8 swap areas could trigger a bogus OOM scenario when swapping out to such a swap area. This update fixes this problem by reducing a return value of the SWP_TYPE_SHIFT() function and removing a broken function call from the read_swap_header() function. (BZ#1099727)

* The automatic route cache rebuilding feature could incorrectly compute the length of a route hash chain if the cache contained multiple entries with the same key but a different TOS, mark, or OIF bit. Consequently, the feature could reach the rebuild limit and disable the routing cache on the system. This problem is fixed by using a helper function that avoids counting such duplicate routes.
(BZ#1113823)

* When booting a guest in the Hyper-V environment and enough of Programmable Interval Timer (PIT) interrupts were lost or not injected into the guest on time, the kernel panicked and the guest failed to boot. This problem has been fixed by bypassing the relevant PIT check when the guest is running under the Hyper-V environment. (BZ#1112225)

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.
