Red Hat Security Advisory 2016-0455-01 – The ruby193 collection provides Ruby version 1.9.3 and Ruby on Rails version 3.2. Ruby on Rails is a model-view-controller framework for web application development. Multiple directory traversal flaws were found in the way the Action View component searched for templates for rendering. If an application passed untrusted input to the ‘render’ method, a remote, unauthenticated attacker could use these flaws to render unexpected files and, possibly, execute arbitrary code. Various other issues were also addressed.
