______________________________________________________________________________

   An update that solves 18 vulnerabilities and has 29 fixes
   is now available.

Description:



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

   The following security bugs were fixed:

   - CVE-2017-5715: Systems with microprocessors utilizing speculative
     execution and indirect branch prediction may allow unauthorized
     disclosure of information to an attacker with local user access via a
     side-channel analysis (bnc#1068032).

     Enhancements and bugfixes over the previous fixes have been added to
   this kernel.

   - CVE-2018-10087: The kernel_wait4 function in kernel/exit.c might have
     allowed local users to cause a denial of service by triggering an
     attempted use of the -INT_MIN value (bnc#1089608).
   - CVE-2018-7757: Memory leak in the sas_smp_get_phy_events function in
     drivers/scsi/libsas/sas_expander.c allowed local users to cause a denial
     of service (memory consumption) via many read accesses to files in the
     /sys/class/sas_phy directory, as demonstrated by the
     /sys/class/sas_phy/phy-1:0:12/invalid_dword_count file (bnc#1084536).
   - CVE-2018-7566: There was a buffer overflow via an
     SNDRV_SEQ_IOCTL_SET_CLIENT_POOL ioctl write operation to /dev/snd/seq by
     a local user (bnc#1083483).
   - CVE-2017-0861: Use-after-free vulnerability in the snd_pcm_info function
     in the ALSA subsystem allowed attackers to gain privileges via
     unspecified vectors (bnc#1088260).
   - CVE-2018-8822: Incorrect buffer length handling in the ncp_read_kernel
     function in fs/ncpfs/ncplib_kernel.c could be exploited by malicious
     NCPFS servers to crash the kernel or execute code (bnc#1086162).
   - CVE-2017-13166: An elevation of privilege vulnerability in the kernel
     v4l2 video driver. (bnc#1072865).
   - CVE-2017-18203: The dm_get_from_kobject function in drivers/md/dm.c
     allowed local users to cause a denial of service (BUG) by leveraging a
     race condition with __dm_destroy during creation and removal of DM
     devices (bnc#1083242).
   - CVE-2017-16911: The vhci_hcd driver allowed allows local attackers to
     disclose kernel memory addresses. Successful exploitation requires that
     a USB device is attached over IP (bnc#1078674).
   - CVE-2017-18208: The madvise_willneed function in mm/madvise.c local
     users to cause a denial of service (infinite loop) by triggering use of
     MADVISE_WILLNEED for a DAX mapping (bnc#1083494).
   - CVE-2017-16644: The hdpvr_probe function in
     drivers/media/usb/hdpvr/hdpvr-core.c allowed local users to cause a
     denial of service (improper error handling and system crash) or possibly
     have unspecified other impact via a crafted USB device (bnc#1067118).
   - CVE-2018-6927: The futex_requeue function in kernel/futex.c in the Linux
     kernel might allow attackers to cause a denial of service (integer
     overflow) or possibly have unspecified other impact by triggering a
     negative wake or requeue value (bnc#1080757).
   - CVE-2017-16914: The "stub_send_ret_submit()" function
     (drivers/usb/usbip/stub_tx.c) allowed attackers to cause a denial of
     service (NULL pointer dereference) via a specially crafted USB over IP
     packet (bnc#1078669).
   - CVE-2016-7915: The hid_input_field function in drivers/hid/hid-core.c
     allowed physically proximate attackers to obtain sensitive information
     from kernel memory or cause a denial of service (out-of-bounds read) by
     connecting a device, as demonstrated by a Logitech DJ receiver
     (bnc#1010470).
   - CVE-2015-5156: The virtnet_probe function in drivers/net/virtio_net.c
     attempted to support a FRAGLIST feature without proper memory
     allocation, which allowed guest OS users to cause a denial of service
     (buffer overflow and memory corruption) via a crafted sequence of
     fragmented packets (bnc#940776).
   - CVE-2017-12190: The bio_map_user_iov and bio_unmap_user functions in
     block/bio.c did unbalanced refcounting when a SCSI I/O vector has small
     consecutive buffers belonging to the same page. The bio_add_pc_page
     function merges them into one, but the page reference is never dropped.
     This causes a memory leak and possible system lockup (exploitable
     against the host OS by a guest OS user, if a SCSI disk is passed through
     to a virtual machine) due to an out-of-memory condition (bnc#1062568).
   - CVE-2017-16912: The "get_pipe()" function (drivers/usb/usbip/stub_rx.c)
     allowed attackers to cause a denial of service (out-of-bounds read) via
     a specially crafted USB over IP packet (bnc#1078673).
   - CVE-2017-16913: The "stub_recv_cmd_submit()" function
     (drivers/usb/usbip/stub_rx.c) when handling CMD_SUBMIT packets allowed
     attackers to cause a denial of service (arbitrary memory allocation) via
     a specially crafted USB over IP packet (bnc#1078672).
