   An update that solves three vulnerabilities and has four
   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-2018-1087: And an unprivileged KVM guest user could use this flaw to
     potentially escalate their privileges inside a guest. (bsc#1087088)
   - CVE-2018-8897: An unprivileged system user could use incorrect set up
     interrupt stacks to crash the Linux kernel resulting in DoS issue.
     (bsc#1087088)
   - CVE-2018-10124: The kill_something_info function in kernel/signal.c in
     the Linux kernel before 4.13, when an unspecified architecture and
     compiler is used, might allow local users to cause a denial of service
     via an INT_MIN argument (bnc#1089752).

   The following non-security bugs were fixed:

   - kvm/x86: fix icebp instruction handling (bsc#1087088).
   - media: cpia2: Fix a couple off by one bugs (bsc#1050431).

______________________________________________________________________________

   An update that solves 20 vulnerabilities and has 11 fixes
   is now available.

Description:



   The SUSE Linux Enterprise 11 SP3 LTSS kernel was updated to receive
   various security and bugfixes.

   The following security bugs were fixed:

   - CVE-2018-1087: And an unprivileged KVM guest user could use this flaw to
     potentially escalate their privileges inside a guest. (bsc#1087088)
   - CVE-2018-8897: An unprivileged system user could use incorrect set up
     interrupt stacks to crash the Linux kernel resulting in DoS issue.
     (bsc#1087088)
   - CVE-2018-10124: The kill_something_info function in kernel/signal.c
     might allow local users to cause a denial of service via an INT_MIN
     argument (bnc#1089752).
   - CVE-2018-10087: The kernel_wait4 function in kernel/exit.c might allow
     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
     1087209).
   - CVE-2018-7566: A Buffer Overflow via an SNDRV_SEQ_IOCTL_SET_CLIENT_POOL
     ioctl write operation to /dev/snd/seq by a local user was fixed
     (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
     allow 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 allowed
     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 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).

   The following non-security bugs were fixed:

   - Integrate fixes resulting from bsc#1088147 More info in the respective
     commit messages.
   - KABI: x86/kaiser: properly align trampoline stack.
   - KEYS: do not let add_key() update an uninstantiated key (bnc#1063416).
   - ipc/msg: introduce msgctl(MSG_STAT_ANY) (bsc#1072689).
   - ipc/sem: introduce semctl(SEM_STAT_ANY) (bsc#1072689).
   - ipc/shm: introduce shmctl(SHM_STAT_ANY) (bsc#1072689).
   - kvm/x86: fix icebp instruction handling (bsc#1087088).
   - leds: do not overflow sysfs buffer in led_trigger_show (bsc#1080464).
   - mm/mmap.c: do not blow on PROT_NONE MAP_FIXED holes in the stack
     (bnc#1039348).
   - x86-64: Move the "user" vsyscall segment out of the data segment
     (bsc#1082424).
   - x86/entry/64: Do not use IST entry for #BP stack (bsc#1087088).
   - x86/kaiser: properly align trampoline stack (bsc#1087260).
   - x86/retpoline: do not perform thunk calls in ring3 vsyscall code
     (bsc#1085331).
   - xfs: check for buffer errors before waiting (bsc#1052943).
   - xfs: fix allocbt cursor leak in xfs_alloc_ag_vextent_near (bsc#1087762).
   - xfs: really fix the cursor leak in xfs_alloc_ag_vextent_near
     (bsc#1087762).

   An update that solves 9 vulnerabilities and has 27 fixes is
   now available.

Description:



   The SUSE Linux Enterprise 12 SP2 LTSS kernel was updated to 4.4.121 to
   receive various security and bugfixes.

   The following security bugs were fixed:

   - CVE-2018-8781: The udl_fb_mmap function in drivers/gpu/drm/udl/udl_fb.c
     had an integer-overflow vulnerability that allowed local users with
     access to the udldrmfb driver to obtain full read and write permissions
     on kernel physical pages, resulting in a code execution in kernel space
     (bnc#1090643).
   - CVE-2018-10124: The kill_something_info function in kernel/signal.c
     might have allowed local users to cause a denial of service via an
     INT_MIN argument (bnc#1089752).
   - 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-2017-18257: The __get_data_block function in fs/f2fs/data.c in the
     Linux kernel allowed local users to cause a denial of service (integer
     overflow and loop) via crafted use of the open and fallocate system
     calls with an FS_IOC_FIEMAP ioctl. (bnc#1088241)
   - 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-2018-8043: The unimac_mdio_probe function in
     drivers/net/phy/mdio-bcm-unimac.c did not validate certain resource
     availability, which allowed local users to cause a denial of service
     (NULL pointer dereference) (bnc#1084829).
   - CVE-2018-7740: The resv_map_release function in mm/hugetlb.c allowed
     local users to cause a denial of service (BUG) via a crafted application
     that made mmap system calls and has a large pgoff argument to the
     remap_file_pages system call (bnc#1084353).
   - CVE-2018-1087: And an unprivileged KVM guest user could use this flaw to
     potentially escalate their privileges inside a guest. (bsc#1087088)
   - CVE-2018-8897: An unprivileged system user could use incorrect set up
     interrupt stacks to crash the Linux kernel resulting in DoS issue.
