How to reproduce it (as minimally and precisely as possible):

1)Create the Dockerfile with this content:

FROM registry.suse.com/suse/sle15:15.5 RUN zypper in -y --no-recommends ruby2.5-rubygem-bundler=1.16.1-3.3.1 ENTRYPOINT [""] CMD ["bash"]

2) Build an image from Dockerfile

docker build -t "suse15.5_test:v1" ./Dockerfile docker run -it suse15.5_test:v1 bash grype suse15.5_test:v1

3) Test with Grype now $ grype --distro sles:15.5 suse15.5_test:v1 rdoc 6.0.1.1 6.1.2.1 gem GHSA-ggxm-pgc9-g7fp High

Anything else we need to know?:
