  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 1003253).

  - CVE-2017-5576, CVE-2017-5577: A buffer overflow in the VC4_SUBMIT_CL
  IOCTL in the VideoCore DRM driver for Raspberry Pi was fixed.
  (bsc#1021294)

  - 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-2017-2583: A Linux kernel built with the Kernel-based Virtual
  Machine (CONFIG_KVM) support was vulnerable to an incorrect segment
  selector(SS) value error. A user/process inside guest could have used
  this flaw to crash the guest resulting in DoS or potentially escalate
  their privileges inside guest. (bsc#1020602).

  - CVE-2017-2584: arch/x86/kvm/emulate.c in the Linux kernel allowed local
  users to obtain sensitive information from kernel memory or cause a
  denial of service (use-after-free) via a crafted application that
  leverages instruction emulation for fxrstor, fxsave, sgdt, and sidt
  (bnc#1019851).

  - CVE-2015-8709: ** DISPUTED ** kernel/ptrace.c in the Linux kernel
  mishandled uid and gid mappings, which allowed local users to gain
  privileges by establishing a user namespace, waiting for a root process
  to enter that namespace with an unsafe uid or gid, and then using the
  ptrace system call.  NOTE: the vendor states 'there is no kernel bug
  here (bnc#959709 bsc#960561).

  - 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-2016-8645: 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-2016-9793: 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 hav ...
