   An update that solves 18 vulnerabilities and has 41 fixes
   is now available.

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).
