RHSA-2013:0154: Critical: Ruby on Rails security update

First published: Thu Jan 10 2013(Updated: )

Ruby on Rails is a model–view–controller (MVC) framework for web<br>application development. Action Pack implements the controller and the view<br>components. Active Record implements object-relational mapping for<br>accessing database entries using objects. Active Support provides support<br>and utility classes used by the Ruby on Rails framework.<br>Multiple flaws were found in the way Ruby on Rails performed XML parameter<br>parsing in HTTP requests. A remote attacker could use these flaws to<br>execute arbitrary code with the privileges of a Ruby on Rails application,<br>perform SQL injection attacks, or bypass the authentication using a<br>specially-created HTTP request. (CVE-2013-0156)<br>Red Hat is aware that a public exploit for the CVE-2013-0156 issues is<br>available that allows remote code execution in applications using Ruby on<br>Rails.<br>Multiple input validation vulnerabilities were discovered in<br>rubygem-activerecord. A remote attacker could possibly use these flaws to<br>perform an SQL injection attack against an application using<br>rubygem-activerecord. (CVE-2012-2661, CVE-2012-2695, CVE-2012-6496,<br>CVE-2013-0155)<br>Multiple input validation vulnerabilities were discovered in<br>rubygem-actionpack. A remote attacker could possibly use these flaws to<br>perform an SQL injection attack against an application using<br>rubygem-actionpack and rubygem-activerecord. (CVE-2012-2660, CVE-2012-2694)<br>Multiple cross-site scripting (XSS) flaws were found in rubygem-actionpack.<br>A remote attacker could use these flaws to conduct XSS attacks against<br>users of an application using rubygem-actionpack. (CVE-2012-3463,<br>CVE-2012-3464, CVE-2012-3465)<br>A flaw was found in the HTTP digest authentication implementation in<br>rubygem-actionpack. A remote attacker could use this flaw to cause a<br>denial of service of an application using rubygem-actionpack and digest<br>authentication. (CVE-2012-3424)<br>Users are advised to upgrade to these updated rubygem-actionpack,<br>rubygem-activesupport, and rubygem-activerecord packages, which resolve<br>these issues. Katello must be restarted ("service katello restart") for<br>this update to take effect.
