These security issues were fixed :

  - CVE-2018-7167: Calling Buffer.fill() or Buffer.alloc()
    with some parameters could have lead to a hang which
    could have resulted in a DoS (bsc#1097375).

  - CVE-2018-7161: By interacting with the http2 server in a
    manner that triggered a cleanup bug where objects are
    used in native code after they are no longer available
    an attacker could have caused a denial of service (DoS)
    by causing a node server providing an http2 server to
    crash (bsc#1097404).

  - CVE-2018-1000168: Fixed a denial of service
    vulnerability by unbundling nghttp2 (bsc#1097401)
