"The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has ruby packages installed that are affected by
multiple vulnerabilities:

  - In Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before
    2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, an
    attacker controlling the unpacking format (similar to
    format string vulnerabilities) can trigger a buffer
    under-read in the String#unpack method, resulting in a
    massive and controlled information disclosure.
    (CVE-2018-8778)

  - RubyGems version Ruby 2.2 series: 2.2.9 and earlier,
    Ruby 2.3 series: 2.3.6 and earlier, Ruby 2.4 series:
    2.4.3 and earlier, Ruby 2.5 series: 2.5.0 and earlier,
    prior to trunk revision 62422 contains a Directory
    Traversal vulnerability in install_location function of
    package.rb that can result in path traversal when
    writing to a symlinked basedir outside of the root. This
    vulnerability appears to have been fixed in 2.7.6.
    (CVE-2018-1000073)

  - In Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before

    Dir.open, Dir.new, Dir.entries and Dir.empty? methods do
    not check NULL characters. When using the corresponding
    method, unintentional directory traversal may be
    performed. (CVE-2018-8780)

  - Directory traversal vulnerability in the Dir.mktmpdir
    method in the tmpdir library in Ruby before 2.2.10,
    2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before
    2.5.1, and 2.6.0-preview1 might allow attackers to
    create arbitrary directories or files via a .. (dot dot)
    in the prefix argument. (CVE-2018-6914)

    2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, an
    attacker can pass a large HTTP request with a crafted
    header to WEBrick server or a crafted body to WEBrick
    server/handler and cause a denial of service (memory
    consumption). (CVE-2018-8777)

  - Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before
    2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1 allows an

vulnerability. An attacker could use this to possibly force the
RubyGems client to download and install gems from a server that the
attacker controls. (CVE-2017-0902)

It was discovered that Ruby incorrectly handled certain YAML files. An
attacker could use this to possibly execute arbitrary code.
