@gabriel19913 great question! What you are seeing is a vulnerability alert for a dependency in the github-slideshow repository. To learn more about security alerts, check out this blog post: https://blog.github.com/2017-11-16-introducing-security-alerts-on-github/
In the meantime, you can fix this by updating the Gemfile.lock file. Simply replace "ffi (1.9.18)" with "ffi (1.9.24)".
