Description Pedro Sampaio 2019-03-25 18:59:31 UTC 
An issue was discovered in RubyGems 2.6 and later through 3.0.2. The gem owner command outputs the contents of the API response directly to stdout. Therefore, if the response is crafted, escape sequence injection may occur.

Comment 1 Pedro Sampaio 2019-03-25 19:14:28 UTC 
Created rubygems tracking bugs for this issue:

Affects: fedora-all [bug 1692530]
Comment 2 Scott Gayou 2019-04-03 22:40:15 UTC 
Flaw is in owner_command.rb

```ruby
    with_response response do |resp|
      owners = Gem::SafeYAML.load clean_text(resp.body)
      say "Owners for gem: #{name}"
      owners.each do |owner|
```
