   An update that solves 30 vulnerabilities and has 72 fixes
   is now available.

Description:


   The SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.74 to receive
   various security and bugfixes.

   Notable new/improved features:
   - Improved support for Hyper-V
   - Support for the tcp_westwood TCP scheduling algorithm

   The following security bugs were fixed:

   - CVE-2017-8106: The handle_invept function in arch/x86/kvm/vmx.c in the
     Linux kernel allowed privileged KVM guest OS users to cause a denial of
     service (NULL pointer dereference and host OS crash) via a
     single-context INVEPT instruction with a NULL EPT pointer (bsc#1035877).
   - CVE-2017-6951: The keyring_search_aux function in
     security/keys/keyring.c in the Linux kernel allowed local users to cause
     a denial of service (NULL pointer dereference and OOPS) via a
     request_key system call for the "dead" type. (bsc#1029850).
   - CVE-2017-2647: The KEYS subsystem in the Linux kernel allowed local
     users to gain privileges or cause a denial of service (NULL pointer
     dereference and system crash) via vectors involving a NULL value for a
     certain match field, related to the keyring_search_iterator function in
     keyring.c. (bsc#1030593)
   - CVE-2016-9604: This fixes handling of keyrings starting with '.'
 in
     KEYCTL_JOIN_SESSION_KEYRING, which could have allowed local users to
     manipulate privileged keyrings (bsc#1035576)
   - 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. (bnc#1033336).
   - CVE-2017-7645: The NFSv2/NFSv3 server in the nfsd subsystem in the Linux
     kernel allowed remote attackers to cause a denial of service (system
     crash) via a long RPC reply, related to net/sunrpc/svc.c,
     fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c. (bsc#1034670).
   - 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-2017-7294: 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-2016-9588: arch/x86/kvm/vmx.c in the Linux kernel mismanaged the #BP
     and #OF exceptions, which allowed guest OS users to cause a denial of
     service (guest OS crash) by declining to handle an exception thrown by
     an L2 guest (bsc#1015703).
   - 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-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-2016-10208: The ext4_fill_super function in fs/ext4/super.c in the
     Linux kernel did not properly validate meta block groups, which allowed
     physically proximate attackers to cause a denial of service
     (out-of-bounds read and system crash) via a crafted ext4 image
     (bnc#1023377).
   - CVE-2017-5897: The ip6gre_err function in net/ipv6/ip6_gre.c in the
     Linux kernel allowed remote attackers to have unspecified impact via
     vectors involving GRE flags in an IPv6 packet, which trigger an
     out-of-bounds access (bsc#1023762).
   - CVE-2017-5986: A 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-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-2016-9191: The cgroup offline implementation in the Linux kernel
     mishandled certain drain operations, which allowed local users to cause
     a denial of service (system hang) by leveraging access to a container
     environment for executing a crafted application (bnc#1008842)
   - 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-2016-10044: The aio_mount function in fs/aio.c in the Linux kernel
     did not properly restrict execute access, which made it easier for local
     users to bypass intended SELinux W^X policy restrictions, and
     consequently gain privileges, via an io_setup system call (bnc#1023992).
   - CVE-2016-3070: The trace_writeback_dirty_page implementation in
     include/trace/events/writeback.h in the Linux kernel improperly
     interacts with mm/migrate.c, which allowed local users to cause a denial
     of service (NULL pointer dereference and system crash) or possibly have
     unspecified other impact by triggering a certain page move (bnc#979215).
   - 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-2017-6345: The LLC subsystem in the Linux kernel did not ensure that
     a certain destructor exists in required circumstances, which allowed
     local users to cause a denial of service (BUG_ON) or possibly have
     unspecified other impact via crafted system calls (bnc#1027190)
   - CVE-2017-6346: Race condition in net/packet/af_packet.c in the Linux
     kernel allowed local users to cause a denial of service (use-after-free)
     or possibly have unspecified other impact via a multithreaded
     application that made PACKET_FANOUT setsockopt system calls (bnc#1027189)
   - 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. NOTE: this
     vulnerability exists because of an incorrect fix for CVE-2017-5986
     (bnc#1027066)
   - 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-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-2016-2117: The atl2_probe function in
     drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel incorrectly
     enables scatter/gather I/O, which allowed remote attackers to obtain
     sensitive information from kernel memory by reading packet data
     (bnc#968697)
   - CVE-2015-1350: The VFS subsystem in the Linux kernel provided an
     incomplete set of requirements for setattr operations that
     underspecifies removing extended privilege attributes, which allowed
     local users to cause a denial of service (capability stripping) via a
     failed invocation of a system call, as demonstrated by using chown to
     remove a capability from the ping or Wireshark dumpcap program
     (bsc#914939).
   - CVE-2016-7117: Use-after-free vulnerability in the __sys_recvmmsg
     function in net/socket.c in the Linux kernel allowed remote attackers to
     execute arbitrary code via vectors involving a recvmmsg system call that
     is mishandled during error processing (bsc#1003077).
