@staaldraad thanks! I got notified of the CVE, so updated the titles of all the related PR's to include it 👍 We should probably update the release notes as well; https://github.com/docker/docker.github.io/blob/master/engine/release-notes.md#18094 Let me know if you're interested in opening a pull request in that repository, or if you want me to do so |

Thanks @thaJeztah 🎉 I've opened a PR -- wanted to tag you in as reviewer but it seems like labels and reviewers aren't available to non-project members |

From a fix that @tonistiigi created, this PR adds validation for git ref so it can't be misinterpreted as a flag.
fetch --is a cleaner option but as it is theoretically possible to also hit it in checkout there's a custom validation as well.Thanks to @staaldraad for pointing this issue out originally.
