  The following security bugs were fixed:

  - CVE-2016-7117: Use-after-free vulnerability in the __sys_recvmmsg
  function in net/socket.c in the Linux kernel allowed remote attackers to
  execute arbitrary code via vectors involving a recvmmsg system call that
  is mishandled during error processing (bnc#1003077).

  - CVE-2017-5551: tmpfs: Fixed a bug that could have allowed users to set
  setgid bits on files they don't down (bsc#1021258).

  - CVE-2016-10147: crypto/mcryptd.c in the Linux kernel allowed local users
  to cause a denial of service (NULL pointer dereference and system crash)
  by using an AF_ALG socket with an incompatible algorithm, as
  demonstrated by mcryptd(md5) (bnc#1020381).

  - CVE-2016-10088: The sg implementation in the Linux kernel did not
  properly restrict write operations in situations where the KERNEL_DS
  option is set, which allowed local users to read or write to arbitrary
  kernel memory locations or cause a denial of service (use-after-free) by
  leveraging access to a /dev/sg device, related to block/bsg.c and
  drivers/scsi/sg.c.  NOTE: this vulnerability exists because of an
  incomplete fix for CVE-2016-9576 (bnc#1017710).

  - 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-2016-8645: The TCP stack in the Linux kernel mishandled skb
  truncation, which allowed local users to cause a denial of service
  (system crash) via a crafted application that made sendto system calls,
  related to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c (bnc#1009969).

  - CVE-2016-9806: Race condition in the netlink_dump function in
  net/netlink/af_netlink.c in the Linux kernel allowed local users to
  cause a denial of service (double free) or possibly have unspecified
  other impact via a crafted application that made sendmsg system calls,
  leading to a free operation associated with a new dump that started
  earlier than anticipated (bnc#1013540 1017589).

  - CVE-2016-9793: The sock_setsockopt function in net/core/sock.c in the
  Linux kernel mishandled negative values of sk_sndbuf and sk_rcvbuf,
  which allowed local users to cause a denial of service (memory
  corruption and system crash) or possibly have unspecified other impact
  by leveraging th ...
