"According to the versions of the ruby packages installed, the EulerOS
Virtualization for ARM 64 installation on the remote host is affected
by the following vulnerabilities :

  - Ruby is an extensible, interpreted, object-oriented,
    scripting language. It has features to process text
    files and to perform system management tasks.Security
    Fix(es):An issue was discovered in the OpenSSL library
    in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before
    2.5.2, and 2.6.x before 2.6.0-preview3. When two
    OpenSSL::X509::Name objects are compared using ==,
    depending on the ordering, non-equal objects may return
    true. When the first argument is one character longer
    than the second, or the second argument contains a
    character that is one less than a character in the same
    position of the first argument, the result of == will
    be true. This could be leveraged to create an
    illegitimate certificate that may be accepted as
    legitimate and then used in signing or encryption
    operations.(CVE-2018-16395)An issue was discovered in
    Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before
    2.5.2, and 2.6.x before 2.6.0-preview3. It does not
    taint strings that result from unpacking tainted
    strings with some formats.(CVE-2018-16396)** RESERVED

    or individual that will use it when announcing a new

    candidate has been reserved by an organization or
    individual that will use it when announcing a new
    security problem. When the candidate has been
    publicized, the details for this candidate will be
    provided.(CVE-2019-8325)An exploitable heap overflow
    vulnerability exists in the Fiddle::Function.new
    ''initialize'' function functionality of Ruby. In
    Fiddle::Function.new ''initialize'' heap buffer
    ''arg_types'' allocation is made based on args array
    length. Specially constructed object passed as element
    of args array can increase this array size after
    mentioned allocation and cause heap
    overflow.(CVE-2016-2339)Type confusion exists in
    _cancel_eval Ruby's TclTkIp class method. Attacker
    passing different type of object than String as
    ''retval'' argument can cause arbitrary code
    execution.(CVE-2016-2337)
