    Description:


    The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various
    security and bugfixes.

    Notable new features:

    - Toleration of newer crypto hardware for z Systems
    - USB 2.0 Link power management for Haswell-ULT

    The following security bugs were fixed:

    - CVE-2017-7308: The packet_set_ring function in net/packet/af_packet.c in
    the Linux kernel did not properly validate certain block-size data,
    which allowed local users to cause a denial of service (overflow) or
    possibly have unspecified other impact via crafted system calls
    (bnc#1031579)
    - CVE-2017-2671: The ping_unhash function in net/ipv4/ping.c in the Linux
    kernel was too late in obtaining a certain lock and consequently could
    not ensure that disconnect function calls are safe, which allowed local
    users to cause a denial of service (panic) by leveraging access to the
    protocol value of IPPROTO_ICMP in a socket system call (bnc#1031003)
    - CVE-2017-7184: The xfrm_replay_verify_len function in
    net/xfrm/xfrm_user.c in the Linux kernel did not validate certain size
    data after an XFRM_MSG_NEWAE update, which allowed local users to obtain
    root privileges or cause a denial of service (heap-based out-of-bounds
    access) by leveraging the CAP_NET_ADMIN capability (bsc#1030573).
    - CVE-2017-5970: The ipv4_pktinfo_prepare function in
    net/ipv4/ip_sockglue.c in the Linux kernel allowed attackers to cause a
    denial of service (system crash) via (1) an application that made
    crafted system calls or possibly (2) IPv4 traffic with invalid IP
    options (bsc#1024938).
    - CVE-2017-7616: Incorrect error handling in the set_mempolicy and mbind
    compat syscalls in mm/mempolicy.c in the Linux kernel allowed local
    users to obtain sensitive information from uninitialized stack data by
    triggering failure of a certain bitmap operation (bsc#1033336).
    - CVE-2017-7294: The vmw_surface_define_ioctl function in
    drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not
    validate addition of certain levels data, which allowed local users to
    trigger an integer overflow and out-of-bounds write, and cause a denial
    of service (system hang or crash) or possibly gain privileges, via a
    crafted ioctl call for a /dev/dri/renderD* device (bnc#1031440)
    - CVE-2017-7261: The vmw_surface_define_ioctl function in
    drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not
    check for a zero value of certain levels data, which allowed local users
    to cause a denial of service (ZERO_SIZE_PTR dereference, and GPF and
    possibly panic) via a crafted ioctl call for a /dev/dri/renderD* device
    (bnc#1031052)
    - CVE-2017-7187: The sg_ioctl function in drivers/scsi/sg.c in the Linux
    kernel allowed local users to cause a denial of service (stack-based
    buffer overflow) or possibly have unspecified other impact via a large
    command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds
    write access in the sg_write function (bnc#1030213)
    - CVE-2017-6348: The hashbin_delete function in net/irda/irqueue.c in the
    Linux kernel improperly managed lock dropping, which allowed local users
    to cause a denial of service (deadlock) via crafted operations on IrDA
    devices (bnc#1027178)
    - CVE-2017-5669: The do_shmat function in ipc/shm.c in the Linux kernel
    did not restrict the address calculated by a certain rounding operation,
    which allowed local users to map page zero, and consequently bypass a
    protection mechanism that exists for the mmap system call, by making
    crafted shmget and shmat system calls in a privileged context
    (bnc#1026914)
    - CVE-2015-3288: mm/memory.c in the Linux kernel mishandled anonymous
    pages, which allowed local users to gain privileges or cause a denial of
    service (page tainting) via a crafted application that triggers writing
    to page zero (bsc#979021).
    - CVE-2016-10200: Race condition in the L2TPv3 IP Encapsulation feature in
    the Linux kernel allowed local users to gain privileges or cause a
    denial of service (use-after-free) by making multiple bind system calls
    without properly ascertaining whether a socket has the SOCK_ZAPPED
    status, related to net/l2tp/l2tp_ip.c and net/l2tp/l2tp_ip6.c
    (bnc#1028415)
    - CVE-2016-5243: The tipc_nl_compat_link_dump function in
    net/tipc/netlink_compat.c in the Linux kernel did not properly copy a
    certain string, which allowed local users to obtain sensitive
    information from kernel stack memory by reading a Netlink message
    (bnc#983212)
    - CVE-2017-6353: net/sctp/socket.c in the Linux kernel did not properly
    restrict association peel-off operations during certain wait states,
    which allowed local users to cause a denial of service (invalid unlock
    and double free) via a multithreaded application (bnc#1027066)
    - CVE-2017-6214: The tcp_splice_read function in net/ipv4/tcp.c in the
    Linux kernel allowed remote attackers to cause a denial of service
    (infinite loop and soft lockup) via vectors involving a TCP packet with
    the URG flag (bnc#1026722)
    - CVE-2017-6074: The dccp_rcv_state_process function in net/dccp/input.c
    in the Linux kernel mishandled DCCP_PKT_REQUEST packet data structures
    in the LISTEN state, which allowed local users to obtain root privileges
    or cause a denial of service (double free) via an application that made
    an IPV6_RECVPKTINFO setsockopt system call (bnc#1026024)
    - CVE-2017-5986: Race condition in the sctp_wait_for_sndbuf function in
    net/sctp/socket.c in the Linux kernel allowed local users to cause a
    denial of service (assertion failure and panic) via a multithreaded
    application that peels off an association in a certain buffer-full state
    (bsc#1025235)
    - CVE-2015-8970: crypto/algif_skcipher.c in the Linux kernel did not
    verify that a setkey operation has been performed on an AF_ALG socket an
    accept system call is processed, which allowed local users to cause a
    denial of service (NULL pointer dereference and system crash) via a
    crafted application that does not supply a key, related to the lrw_crypt
    function in crypto/lrw.c (bsc#1008374).
