How to fix?

Upgrade Alpine:3.8 ruby to version 2.5.5-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby package and not the ruby package as distributed by Alpine. See How to fix? for Alpine:3.8 relevant fixed versions and status.

An issue was discovered in RubyGems 2.6 and later through 3.0.2. Gem::GemcutterUtilities#with_response may output the API response to stdout as it is. Therefore, if the API side modifies the response, escape sequence injection may occur.
