"- CVE-2018-5391 (FragmentSmack)
    Juha-Matti Tilli discovered a flaw in the way the Linux
    kernel handled reassembly of fragmented IPv4 and IPv6
    packets. A remote attacker can take advantage of this
    flaw to trigger time and calculation expensive fragment
    reassembly algorithms by sending specially crafted
    packets, leading to remote denial of service.

  This is mitigated by reducing the default limits on memory usage for
  incomplete fragmented packets. The same mitigation can be achieved
  without the need to reboot, by setting the sysctls :

    net.ipv4.ipfrag_low_thresh = 196608 net.ipv6.ip6frag_low_thresh =
    196608 net.ipv4.ipfrag_high_thresh = 262144
    net.ipv6.ip6frag_high_thresh = 262144

  The default values may still be increased by local configuration if
  necessary."
