  script_tag(name:"insight", value:"The openSUSE Leap 42.2 kernel was updated to 4.4.36 to receive various
  security and bugfixes.

  The following security bugs were fixed:

  - CVE-2015-1350: The VFS subsystem in the Linux kernel 3.x provides 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
  (bnc#914939).

  - CVE-2015-8964: The tty_set_termios_ldisc function in
  drivers/tty/tty_ldisc.c in the Linux kernel allowed local users to
  obtain sensitive information from kernel memory by reading a tty data
  structure (bnc#1010507).

  - CVE-2016-7042: The proc_keys_show function in security/keys/proc.c in
  the Linux kernel through 4.8.2, when the GNU Compiler Collection (gcc)
  stack protector is enabled, uses an incorrect buffer size for certain
  timeout data, which allowed local users to cause a denial of service
  (stack memory corruption and panic) by reading the /proc/keys file
  (bnc#1004517).

  - CVE-2016-7913: The xc2028_set_config function in
  drivers/media/tuners/tuner-xc2028.c in the Linux kernel allowed local
  users to gain privileges or cause a denial of service (use-after-free)
  via vectors involving omission of the firmware name from a certain data
  structure (bnc#1010478).

  - CVE-2016-7917: The nfnetlink_rcv_batch function in
  net/netfilter/nfnetlink.c in the Linux kernel did not check whether a
  batch message's length field is large enough, which allowed local users
  to obtain sensitive information from kernel memory or cause a denial of
  service (infinite loop or out-of-bounds read) by leveraging the
  CAP_NET_ADMIN capability (bnc#1010444).

  - CVE-2016-8632: The tipc_msg_build function in net/tipc/msg.c in the
  Linux kernel did not validate the relationship between the minimum
  fragment length and the maximum packet size, which allowed local users
  to gain privileges or cause a denial of service (heap-based buffer
  overflow) by leveraging the CAP_NET_ADMIN capability (bnc#1008831).

  - CVE-2016-8655: A race condition in the af_packet packet_set_ring
  function could be used by local attackers to crash the kernel or gain
  privileges (bsc#1012754).

  - CVE-2016-8666: The IP stack in the Linux kernel allowed remote attackers
  to cause a denial of service (stack consumption and panic) or possibly
  have unspecified other impact by triggering use of the GRO path for
  packets with tunnel stacking, as dem ...
