    Description:


    The SUSE Linux Enterprise 11 Service Pack 3 Real Time Extension kernel has
    been updated to fix various bugs and security issues.

    The following security bugs have been fixed:

    *

    CVE-2012-2372: The rds_ib_xmit function in net/rds/ib_send.c in the
    Reliable Datagram Sockets (RDS) protocol implementation in the Linux
    kernel 3.7.4 and earlier allows local users to cause a denial of service
    (BUG_ON and kernel panic) by establishing an RDS connection with the
    source IP address equal to the IPoIB interfaces own IP address, as
    demonstrated by rds-ping. (bnc#767610)

    *

    CVE-2013-2929: The Linux kernel before 3.12.2 does not properly use
    the get_dumpable function, which allows local users to bypass intended
    ptrace restrictions or obtain sensitive information from IA64 scratch
    registers via a crafted application, related to kernel/ptrace.c and
    arch/ia64/include/asm/processor.h. (bnc#847652)

    *

    CVE-2013-4299: Interpretation conflict in
    drivers/md/dm-snap-persistent.c in the Linux kernel through 3.11.6 allows
    remote authenticated users to obtain sensitive information or modify data
    via a crafted mapping to a snapshot block device. (bnc#846404)

    drivers/net/wireless/ath/ath9k/htc_drv_main.c in the Linux kernel through
    3.12 uses a BSSID masking approach to determine the set of MAC addresses
    on which a Wi-Fi device is listening, which allows remote attackers to
    discover the original MAC address after spoofing by sending a series of
    packets to MAC addresses with certain bit manipulations. (bnc#851426)

    *

    CVE-2013-6382: Multiple buffer underflows in the XFS implementation
    in the Linux kernel through 3.12.1 allow local users to cause a denial of
    service (memory corruption) or possibly have unspecified
    other impact by leveraging the CAP_SYS_ADMIN capability for a (1)
    XFS_IOC_ATTRLIST_BY_HANDLE or (2) XFS_IOC_ATTRLIST_BY_HANDLE_32 ioctl call
    with a crafted length value, related to the xfs_attrlist_by_handle
    function in fs/xfs/xfs_ioctl.c and the xfs_compat_attrlist_by_handle
    function in fs/xfs/xfs_ioctl32.c. (bnc#852553)

    *

    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. (bnc#869563)

    *

    CVE-2014-0055: The get_rx_bufs function in drivers/vhost/net.c in
    the vhost-net subsystem in the Linux kernel package before 2.6.32-431.11.2
    on Red Hat Enterprise Linux (RHEL) 6 does not properly handle
    vhost_get_vq_desc errors, which allows guest OS users to cause a denial of
    service (host OS crash) via unspecified vectors. (bnc#870173)

    *

    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. (bnc#870576)

    *

    CVE-2014-0101: The sctp_sf_do_5_1D_ce function in
    net/sctp/sm_statefuns.c in the Linux kernel through 3.13.6 does not
    validate certain auth_enable and auth_capable fields before making an
    sctp_sf_authenticate call, which allows remote attackers to cause a denial
    of service (NULL pointer dereference and system crash) via an SCTP
    handshake with a modified INIT chunk and a crafted AUTH chunk before a
    COOKIE_ECHO chunk. (bnc#866102)

    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.
    (bnc#863335)

    *

    CVE-2014-2309: The ip6_route_add function in net/ipv6/route.c in the
    Linux kernel through 3.13.6 does not properly count the addition of
    routes, which allows remote attackers to cause a denial of service (memory
    consumption) via a flood of ICMPv6 Router Advertisement packets.
    (bnc#867531)

    *

    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.
    (bnc#868653)

    *

    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

    *

    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. (bnc#873374)

    *

    CVE-2014-3122: The try_to_unmap_cluster function in mm/rmap.c in the
    Linux kernel before 3.14.3 does not properly consider which pages must be
    locked, which allows local users to cause a denial of service (system
    crash) by triggering a memory-usage pattern that requires removal of
    page-table mappings. (bnc#876102)

    *

    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. (bnc#877257)

    *

    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.
    (bnc#877257)

    *

    CVE-2014-3917: kernel/auditsc.c in the Linux kernel through 3.14.5,
    when CONFIG_AUDITSYSCALL is enabled with certain syscall rules, allows
    local users to obtain potentially sensitive single-bit values from kernel
    memory or cause a denial of service (OOPS) via a large value of a syscall
    number. (bnc#880484)

    *

    CVE-2014-4508: arch/x86/kernel/entry_32.S in the Linux kernel
    through 3.15.1 on 32-bit x86 platforms, when syscall auditing is enabled
    and the sep CPU feature flag is set, allows local users to cause a denial
    of service (OOPS and system crash) via an invalid syscall number, as
    demonstrated by number
