Description

Updated rubygem-actionpack, rubygem-activesupport, ruby193-rubygem-actionpack, and ruby193-rubygem-activesupport packages that fix multiple security issues are now available for Red Hat OpenShift Enterprise 1.0.

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. (CVE-2013-0156)

Red Hat is aware that a public exploit for the CVE-2013-0156 issues is available that allows remote code execution in applications using Ruby on Rails.

All users of Red Hat OpenShift Enterprise are advised to upgrade to these updated packages, which correct these issues. For Red Hat OpenShift Enterprise administrators, the openshift-broker and openshift-console services must be restarted for this update to take effect. Users of OpenShift are advised to update their own applications that are running Ruby on Rails.
