The Red Hat Security Response Team has rated this update as having critical security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
Ruby on Rails is a model-view-controller (MVC) framework for web application development. Action Pack implements the controller and the view components. Active Support provides support and utility classes used by the Ruby on Rails framework.
Multiple flaws were found in the way Ruby on Rails performed XML parameter parsing in HTTP requests. A remote attacker could use these flaws 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 HTTP request.
