   An update that solves four vulnerabilities and has 5 fixes
   is now available.

Description:


   The openSUSE Leap 42.1 was updated to 4.1.27 to receive various security
   and bugfixes.

   The following security bugs were fixed:
   - CVE-2016-4997: A buffer overflow in 32bit compat_setsockopt iptables
     handling could lead to a local privilege escalation. (bsc#986362)
   - CVE-2016-5829: Multiple heap-based buffer overflows in the
     hiddev_ioctl_usage function in drivers/hid/usbhid/hiddev.c in the Linux
     kernel allow local users to cause a denial of service or possibly have
     unspecified other impact via a crafted (1) HIDIOCGUSAGES or (2)
     HIDIOCSUSAGES ioctl call (bnc#986572).
   - CVE-2016-4470: The key_reject_and_link function in security/keys/key.c
     in the Linux kernel did not ensure that a certain data structure is
     initialized, which allowed local users to cause a denial of service
     (system crash) via vectors involving a crafted keyctl request2 command
     (bnc#984755).
   - CVE-2016-4794: Use-after-free vulnerability in mm/percpu.c in the Linux
     kernel allowed local users to cause a denial of service (BUG)
     or possibly have unspecified other impact via crafted use of the mmap
      and bpf system calls (bnc#980265).

   The following non-security bugs were fixed:
   - Refresh patches.xen/xen-netback-coalesce: Restore copying of SKBs with
     head exceeding page size (bsc#978469).
   - Refresh patches.xen/xen3-patch-2.6.26 (fix PAT initialization).
   - Refresh patches.xen/xen3-patch-2.6.39 (fix ia32_compat inheritance).
   - Refresh patches.xen/xen3-patch-3.14: Suppress atomic file position
     updates for /proc/xen/xenbus (bsc#970275).
   - Refresh patches.xen/xen3-patch-3.16 (drop redundant addition of a
     comment).
   - Refresh patches.xen/xen3-patch-4.1.7-8.
   - base: make module_create_drivers_dir race-free (bnc#983977).
   - ipvs: count pre-established TCP states as active (bsc#970114).
   - net: thunderx: Fix TL4 configuration for secondary Qsets (bsc#986530).
   - net: thunderx: Fix link status reporting (bsc#986530).
