For people applying the security patches, please beware that Rails 3.2.11 has broken some things (I've been having issues related to bad JSON parsing).
Fortunately, the community is stepping up with patches[1]. Hopefully, these patches are not adding further vulnerabilities.
This will install version 3.2.8a. If you get a bundler error "NoMethodError: undefined method [] for nil:NilClass", try upgrading your rubygems-bundler gem to version 1.1.0.
