Several vulnerabilities were discovered in Action Pack, a component of Ruby on Rails.
actionview/lib/action_view/helpers/number_helper.rb contains multiple cross-site scripting vulnerabilities
actionpack/lib/action_view/template/text.rb performs symbol interning on MIME type strings, allowing remote denial-of-service attacks via increased memory consumption.
A directory traversal vulnerability in actionpack/lib/abstract_controller/base.rb allows remote attackers to read arbitrary files.
For the stable distribution (wheezy), these problems have been fixed in version 3.2.6-6+deb7u2.
We recommend that you upgrade your ruby-actionpack-3.2 packages.
