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

  - The JSON gem through 2.2.0 for Ruby, as used in Ruby
    2.4 through 2.4.9, 2.5 through 2.5.7, and 2.6 through
    2.6.5, has an Unsafe Object Creation Vulnerability.
    This is quite similar to CVE-2013-0269, but does not
    rely on poor garbage-collection behavior within Ruby.
    Specifically, use of JSON parsing methods can lead to
    creation of a malicious object within the interpreter,
    with adverse effects that are
    application-dependent.(CVE-2020-10663)

  - An issue was discovered in Ruby 2.5.x through 2.5.7,
    2.6.x through 2.6.5, and 2.7.0. If a victim calls
    BasicSocket#read_nonblock(requested_size, buffer,
    exception: false), the method resizes the buffer to fit
    the requested size, but no data is copied. Thus, the
    buffer string provides the previous value of the heap.
    This may expose possibly sensitive data from the
    interpreter.(CVE-2020-10933)

Note that Tenable Network Security has extracted the preceding
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.");

"When parsing certain JSON documents, the json gem (including the one
bundled with Ruby) can be coerced into creating arbitrary objects in
the target system.

This is the same issue as CVE-2013-0269. The previous fix was
incomplete, which addressed JSON.parse(user_input), but didn't
address some other styles of JSON parsing including JSON(user_input)
and JSON.parse(user_input, nil).

See CVE-2013-0269 in detail. Note that the issue was exploitable to
cause a Denial of Service by creating many garbage-uncollectable
Symbol objects, but this kind of attack is no longer valid because
Symbol objects are now garbage-collectable. However, creating
arbitrary bjects may cause severe security consequences depending upon
the application code.

Please update the json gem to version 2.3.0 or later. You can use gem
update json to update it. If you are using bundler, please add gem
'json', '>= 2.3.0' to your Gemfile."
