We have just released GitLab Community Edition 6.3.1 and GitLab Enterprise Edition 6.3.1 in response to this week's Ruby on Rails security update 3.2.16. We advise all our users to upgrade to GitLab Community Edition 6.3.1 or GitLab Enterprise Edition 6.3.1 immediately.
Ruby on Rails security update 3.2.16 addresses four security issues, including denial of service through memory exhaustion.
Versions affected: all
Versions fixed: GitLab Community Edition 6.3.1, GitLab Enterprise Edition 6.3.1
Users who cannot upgrade can address address the DoS vulnerability by applying this patch based on the workaround provided by Rails in
git am and restarting GitLab.
