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 (MVC) 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. (CVE-2014-0130)
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. (CVE-2013-1854)
Two cross-site scripting (XSS) flaws were found in Action Pack. A remote attacker could use these flaws to conduct XSS attacks against users of an application using Action Pack. (CVE-2013-1855, CVE-2013-1857)
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)
