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.
