  16.04 LTS. Jann Horn discovered that microprocessors utilizing speculative
  execution and indirect branch prediction may allow unauthorized memory reads via
  sidechannel attacks. This flaw is known as Meltdown. A local attacker could use
  this to expose sensitive information, including kernel memory. (CVE-2017-5754)
  Jann Horn discovered that the Berkeley Packet Filter (BPF) implementation in the
  Linux kernel did not properly check the relationship between pointer values and
  the BPF stack. A local attacker could use this to cause a denial of service
  (system crash) or possibly execute arbitrary code. (CVE-2017-17863) Jann Horn
  discovered that the Berkeley Packet Filter (BPF) implementation in the Linux
  kernel improperly performed sign extension in some situations. A local attacker
  could use this to cause a denial of service (system crash) or possibly execute
  arbitrary code. (CVE-2017-16995) Alexei Starovoitov discovered that the Berkeley
  Packet Filter (BPF) implementation in the Linux kernel contained a
  branch-pruning logic issue around unreachable code. A local attacker could use
  this to cause a denial of service. (CVE-2017-17862) Jann Horn discovered that
