CVE-2013-1854

El componente Active Record en Ruby on Rails v2.3.x anterior a v2.3.18, v3.1.x anterior a v3.1.12, y v3.2.x anterior a v3.2.13, procesa determinadas consultas mediante la conversión de los hash de las claves a símbolos, lo que permite a atacantes remotos provocar una denegación de servicio a través de una entrada manipulada al método "where".

A flaw was found in the way Ruby on Rails handled hashes in certain queries. A remote attacker could use this flaw to perform a denial of service (resource consumption) attack by sending specially crafted queries that would result in the creation of Ruby symbols, which were never garbage collected.

Red Hat Subscription Asset Manager acts as a proxy for handling subscription information and software updates on client machines. Red Hat Subscription Asset Manager is built on Ruby on Rails, a model-view-controller framework for web application development. Action Pack implements the controller and the view components. A directory traversal flaw was found in the way Ruby on Rails handled wildcard segments in routes with implicit rendering. A remote attacker could use this flaw to retrieve arbitrary local files accessible to a Ruby on Rails application using the aforementioned routes via a specially crafted request.
