Cross-site scripting (XSS) vulnerability in the number_to_currency helper in actionpack/lib/action_view/helpers/number_helper.rb in Ruby on Rails before 3.2.16 and 4.x before 4.0.2 allows remote attackers to inject arbitrary web script or HTML via the unit parameter.

Updated Subscription Asset Manager 1.4 packages that fix multiple security issues are now available.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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)

Red Hat would like to thank Ruby on Rails upstream for reporting these issues. Upstream acknowledges Ben Murphy as the original reporter of CVE-2013-1854, Charlie Somerville as the original reporter of CVE-2013-1855, Alan Jenkins as the original reporter of CVE-2013-1857, Peter McLarnan as the original reporter of CVE-2013-4491, Toby Hsieh as the original reporter of CVE-2013-6414, and Ankit Gupta as the original reporter of CVE-2013-6415.

All Subscription Asset Manager users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

Toby Hsieh, Peter McLarnan, Ankit Gupta, Sudhir Rao and Kevin Reintjes discovered multiple cross-site scripting and denial of service vulnerabilities in Ruby Actionpack.

According to its self-reported version number, the Puppet Enterprise 3.x install on the remote host is prior to 3.1.1.  As a result, it is reportedly affected by multiple vulnerabilities :

  - An input validation error exists related to the     included Ruby version, handling string to floating point     conversions that could allow denial of service attacks     or arbitrary code execution. (CVE-2013-4164)

  - An error exists related to the included RubyGems     version and 'gem build', 'Gem::Package', and     'Gem::PackageTask' API calls that could allow denial     of service attacks. (CVE-2013-4363)

  - An error exists in the 'i18n' gem for Ruby that could     allow cross-site scripting attacks. (CVE-2013-4491)

  - An error exists related to handling temporary files     that could allow a local attacker to overwrite files by     using a symlink attack. (CVE-2013-4969)

  - An error exists related to the included Ruby on Rails,     'Action View', and handling certain headers that could     allow denial of service attacks. (CVE-2013-6414)

  - An input validation error exists related to the     included Ruby on Rails and the 'unit' parameter in the     'number_to_currency' helper that could allow cross-site     scripting attacks. (CVE-2013-6415)

  - An input validation error exists related to the     included Ruby on Rails, JSON parameter parsing and SQL     queries that could allow SQL injection attacks.
