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

    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).
