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 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|
```
