Historical vulnerability data for the FFmpeg encoding library

The Build

Every push and pull request is run against our integrity checkers on GitHub actions. Click on the above tag to see the status of the build.

For SWEN 331 students

Please see your course website for instructions. This README is more for people managing this data.

Testing project locally

1. You'll need Ruby 2.7+ (get the latest)
2. Run gem install bundler (if you don't already have bundler)
3. cd to the root of this repo, run bundle install
4. Run bundle exec rake

If the output has no failures, then it checks out!

Cloning the source repo

To clone the repo into this folder, use this command:

[e-mail]:FFmpeg/FFmpeg.git tmp/src

Populating New CVEs

Merge Student CVE assignment

NOTE: This is not been merged into VHP yet - these are hypothetical instructions.

Here's how you merge in student data once the assignment is finished.

1. Make sure the current dev branch is updated and works with the build
2. Switch vulnerability-history locally to pull from dev instead of master.
3. Squash and merge the student pull req into dev
4. Run rails data:ffmpeg locally. When it says "Loading data version " and then a git hash, make sure that matches up with the latest merge you just made (so you know you are pulling the latest chromium-vulnerabilities data). Alternatively, you can do rails data:clear data:ffmpeg:load_only which goes quicker.
5. If all is well, then do any spot-checks of their data to make sure everything got tagged just fine.
6. If all is not well:

• You may need to merge their changes with any of your changes. This might be on GitHub itself, or locally.
• You may need to correct their YML structure to make it compatible with the loader. Make the change locally and push back to dev to fix it and re-run.
• If things fail on an exception, you can always put in this snippet somewhere to figure out what file failed and use byebug to figure out the problem:

begin
  # code where things when wrong
rescue
  byebug
end

• You can always do rails data:ffmpeg:nogit to reload things without hitting GitHub - helpful for quicker debugging.

After Merging in New CVEs

After we merge in a bunch of PRs, here's a checklist of what needs updating, and in what order:

• Add mentioned commits (default options should be good enough)
• Generate weeklies (skip existing)
