Three new vulnerabilities have been fixed for Ruby on Rails, on which Gitorious is built. Read the original Ruby on Rails sec-list announcements for further details.
The steps for upgrading are, as usual (from within the root gitorious clone/source directory):
git fetch --tags git merge v2.4.12 git submodule update --init bundle install
We advise all users running their own Gitorious servers to upgrade immediately. Note that the Gitorious Community Edition installer has also been updated to install v2.4.12 now.

Don’t forget to tag these as releases or they won’t show up in the releases list (which is what google takes you to if you search for gitorious release).
