  script_tag(name:"insight", value:"The openSUSE Leap 42.2 kernel was updated
  to 4.4.70 to receive various security and bugfixes. The following security bugs
  were fixed: - CVE-2017-9076: The dccp_v6_request_recv_sock function in
  net/dccp/ipv6.c in the Linux kernel mishandled inheritance, which allowed local
  users to cause a denial of service or possibly have unspecified other impact via
  crafted system calls, a related issue to CVE-2017-8890 (bnc#1039885). -
  CVE-2017-9077: The tcp_v6_syn_recv_sock function in net/ipv6/tcp_ipv6.c in the
  Linux kernel mishandled inheritance, which allowed local users to cause a denial
  of service or possibly have unspecified other impact via crafted system calls, a
  related issue to CVE-2017-8890 (bnc#1040069). - CVE-2017-9075: The
  sctp_v6_create_accept_sk function in net/sctp/ipv6.c in the Linux kernel
  mishandled inheritance, which allowed local users to cause a denial of service
  or possibly have unspecified other impact via crafted system calls, a related
  issue to CVE-2017-8890 (bnc#1039883). - CVE-2017-9074: The IPv6 fragmentation
  implementation in the Linux kernel did not consider that the nexthdr field may
  be associated with an invalid option, which allowed local users to cause a
  denial of service (out-of-bounds read and BUG) or possibly have unspecified
  other impact via crafted socket and send system calls (bnc#1039882). -
  CVE-2017-7487: The ipxitf_ioctl function in net/ipx/af_ipx.c in the Linux kernel
  mishandled reference counts, which allowed local users to cause a denial of
  service (use-after-free) or possibly have unspecified other impact via a failed
  SIOCGIFADDR ioctl call for an IPX interface (bnc#1038879). - CVE-2017-8890: The
  inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c in the Linux
  kernel allowed attackers to cause a denial of service (double free) or possibly
  have unspecified other impact by leveraging use of the accept system call
  (bnc#1038544). - CVE-2017-9150: The do_check function in kernel/bpf/verifier.c
  in the Linux kernel did not make the allow_ptr_leaks value available for
  restricting the output of the print_bpf_insn function, which allowed local users
  to obtain sensitive address information via crafted bpf system calls
  (bnc#1040279). - CVE-2017-7645: The NFSv2/NFSv3 server in the nfsd subsystem in
  the Linux kernel allowed remote attackers to cause a denial of service (system
  crash) via a long RPC reply, related to net/sunrpc/svc.c, fs/nfsd/nfs3xdr.c, and
  fs/nfsd/nfsxdr.c. (bsc#1034670) The following non-security bugs were fixed: -
