One of security fixes impacts all users and is related to HTML escaping code. The other two fixes impacts people using select_tag's prompt option and strip_tags helper from ActionPack.
Rails 3.2.8 is now in the tree. I hope to get to the older versions in the weekend.

Thanks, Hans. Please don't forget to remove vulnerable versions. Closing noglsa for ~arch only.
