  script_tag(name:"insight", value:"The openSUSE Leap 42.3 kernel was updated to 4.4.132 to receive various
  security and bugfixes.

  The following security bugs were fixed:

  - CVE-2018-3639: Information leaks using 'Memory Disambiguation' feature
  in modern CPUs were mitigated, aka 'Spectre Variant 4' (bnc#1087082).

  A new boot commandline option was introduced,
  'spec_store_bypass_disable', which can have following values:

  - auto: Kernel detects whether your CPU model contains an implementation
  of Speculative Store Bypass and picks the most appropriate mitigation.

  - on: disable Speculative Store Bypass

  - off: enable Speculative Store Bypass

  - prctl: Control Speculative Store Bypass per thread via prctl.
  Speculative Store Bypass is enabled for a process by default. The
  state of the control is inherited on fork.

  - seccomp: Same as 'prctl' above, but all seccomp threads will disable
  SSB unless they explicitly opt out.

  The default is 'seccomp', meaning programs need explicit opt-in into the
  mitigation.

  Status can be queried via the
  /sys/devices/system/cpu/vulnerabilities/spec_store_bypass file, containing:

  - 'Vulnerable'

  - 'Mitigation: Speculative Store Bypass disabled'

  - 'Mitigation: Speculative Store Bypass disabled via prctl'

  - 'Mitigation: Speculative Store Bypass disabled via prctl and seccomp'

  - CVE-2017-18257: The __get_data_block function in fs/f2fs/data.c allowed
  local users to cause a denial of service (integer overflow and loop) via
  crafted use of the open and fallocate system calls with an FS_IOC_FIEMAP
  ioctl. (bnc#1088241)

  - CVE-2018-1130: Linux kernel was vulnerable to a null pointer dereference
  in dccp_write_xmit() function in net/dccp/output.c in that allowed a
  local user to cause a denial of service by a number of certain crafted
  system calls (bnc#1092904).

  - CVE-2018-5803: An error in the _sctp_make_chunk() function when handling
  SCTP, packet length could have been exploited by a malicious local user
  to cause a kernel crash and a DoS. (bnc#1083900).

  - CVE-2018-1065: The netfilter subsystem mishandled the case of a rule
  blob that contains a jump but lacks a user-defined chain, which allowed
  local users to cause a denial of service (NULL pointer dereference) by
  leveraging the CAP_NET_RAW or CAP_NET_ADMIN capability, related to
  arpt_do_table in net/ipv4/netfilter/arp_tables.c, ipt_do_table in
  net/ipv4/netfilter/ip_tables.c, and ip6t_do_table in
  net/ipv6/netfilter/ip6_tables.c (bnc#1083650).

  - CVE-2018-7492: A NULL pointer dereference was found in the
  net/rds/rdma.c __rds_rdma_map() function that allowed local attackers to
