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. 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.
