How to fix?

Upgrade Debian:10 ruby2.5 to version 2.5.5-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby2.5 package and not the ruby2.5 package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

An issue was discovered in RubyGems 2.6 and later through 3.0.2. A crafted gem with a multi-line name is not handled correctly. Therefore, an attacker could inject arbitrary code to the stub line of gemspec, which is eval-ed by code in ensure_loadable_spec during the preinstall check.
