Hi We are using logstash 8.12.2 in our setup in docker. Due to security reasons, we need to know what are the versions of the following components used in this version- 1. giflib 2. lcms 3. libnss-nis 4. libnss-nisplus 5. logstash-env2yaml 6. xpp Could not find anything in the documentation and googling doesn't work either. Any help will be really appreciated. Thanks in advance. ---

You can check the packages the docker image uses in the [docker hub](https://hub.docker.com/layers/library/logstash/8.12.2/images/sha256-a15a827088a01c634bb4efe6676f3b5b9f2c8dd50728c56512d61e5cd145b8b2?context=explore). But besides the `env2yaml` I don't think the others are even used. ---
