"The remote EulerOS host is missing multiple security updates.");
  script_set_attribute(attribute:"description", value:
"According to the versions of the golang packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - Some HTTP/2 implementations are vulnerable to ping
    floods, potentially leading to a denial of service. The
    attacker sends continual pings to an HTTP/2 peer,
    causing the peer to build an internal queue of
    responses. Depending on how efficiently this data is
    queued, this can consume excess CPU, memory, or
    both.(CVE-2019-9512)

  - Some HTTP/2 implementations are vulnerable to a reset
    flood, potentially leading to a denial of service. The
    attacker opens a number of streams and sends an invalid
    request over each stream that should solicit a stream
    of RST_STREAM frames from the peer. Depending on how
    the peer queues the RST_STREAM frames, this can consume
    excess memory, CPU, or both.(CVE-2019-9514)

  - net/url in Go before 1.11.13 and 1.12.x before 1.12.8
    mishandles malformed hosts in URLs, leading to an
    authorization bypass in some applications. This is
    related to a Host field with a suffix appearing in
    neither Hostname() nor Port(), and is related to a
    non-numeric port number. For example, an attacker can
    compose a crafted javascript:// URL that results in a
    hostname of google.com.(CVE-2019-14809)

description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
