Summary: Updated ruby193-rubygem-actionpack packages that fix multiple security issues are now available for Red Hat Software Collections 1. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Software Collections for RHEL 6 Server - noarch Red Hat Software Collections for RHEL 6 Workstation - noarch 3. Description: Ruby on Rails is a model-view-controller (MVC) framework for web application development. Action Pack implements the controller and the view components. A flaw was found in the way Ruby on Rails performed JSON parameter parsing. An application using a third party library, which uses the Rack::Request interface, or custom Rack middleware could bypass the protection implemented to fix the CVE-2013-0155 vulnerability, causing the application to receive unsafe parameters and become vulnerable to CVE-2013-0155. (CVE-2013-6417) It was discovered that the internationalization component of Ruby on Rails could, under certain circumstances, return a fallback HTML string that contained user input. A remote attacker could possibly use this flaw to perform a reflective cross-site scripting (XSS) attack by providing a specially crafted input to an application using the aforementioned component. (CVE-2013-4491) A denial of service flaw was found in the header handling component of Action View. A remote attacker could send strings in specially crafted headers that would be cached indefinitely, which would result in all available system memory eventually being consumed. (CVE-2013-6414) It was found that the number_to_currency Action View helper did not properly escape the unit parameter. An attacker could use this flaw to perform a cross-site scripting (XSS) attack on an application that uses data submitted by a user in the unit parameter. (CVE-2013-6415) All ruby193-rubygem-actionpack users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network.
