Service Interruptions

1440: Gitlab security problem

A security issue was found in our gitlab installation. However the version we have installed doesn’t look to be vulnerable (we are running the exploit ourselves and getting no results). Meanwhile we are working on upgrading our GitLab installation(s) to make it easier to follow newer GitLab releases. We are aware of the Mattermost/GitLab split, but without an alternative, we need Mattermost to keep on running. We are planning to upgrade gitlab.science.ru.nl on Thursday September 17th, this will involve some downtime for both gitlab and mattermost.
