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.

It was found that several number conversion helpers in Action View did not properly escape all their parameters. An attacker could use these flaws to perform a cross-site scripting (XSS) attack on an application that uses data submitted by a user as parameters to the affected helpers. (CVE-2014-0081)

A memory consumption issue was discovered in the text rendering component of Action View. A remote attacker could use this flaw to perform a denial of service attack by sending specially crafted queries that would result in the creation of Ruby symbols that were never garbage collected. (CVE-2014-0082)

Red Hat would like to thank the Ruby on Rails Project for reporting these issues. Upstream acknowledges Kevin Reintjes as the original reporter of CVE-2014-0081, and Toby Hsieh of SlideShare as the original reporter of CVE-2014-0082.

All ruby193-rubygem-actionpack users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
