Red Hat Security Advisory 2013-0203-01 - Ruby on Rails is a model–view–controller framework for web application development. Active Support provides support and utility classes used by the Ruby on Rails framework. A flaw was found in the way Active Support performed the parsing of JSON requests by translating them to YAML. A remote attacker could use this flaw to execute arbitrary code with the privileges of a Ruby on Rails application, perform SQL injection attacks, or bypass the authentication using a specially-created JSON request.
