  script_tag(name:"insight", value:"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).
