actionpack Improper Authentication vulnerability
The `decode_credentials` method in `actionpack/lib/action_controller/metal/http_authentication.rb` in Ruby on Rails before 3.0.16, 3.1.x before 3.1.7, and 3.2.x before 3.2.7 converts Digest Authentication strings to symbols, which allows remote attackers to cause a denial of service by leveraging access to an application that uses a `with_http_digest` helper method, as demonstrated by the `authenticate_or_request_with_http_digest` method.

actionpack allows remote attackers to bypass database-query restrictions, perform NULL checks via crafted request
`actionpack/lib/action_dispatch/http/request.rb` in Ruby on Rails before 3.0.14, 3.1.x before 3.1.6, and 3.2.x before 3.2.6 does not properly consider differences in parameter handling between the Active Record component and the Rack interface, which allows remote attackers to bypass intended database-query restrictions and perform NULL checks via a crafted request, as demonstrated by certain `['xyz', nil]` values, a related issue to CVE-2012-2660.

actionpack Cross-site Scripting vulnerability
Cross-site scripting (XSS) vulnerability in `actionpack/lib/action_view/helpers/form_tag_helper.rb` in Ruby on Rails 3.x before 3.0.17, 3.1.x before 3.1.8, and 3.2.x before 3.2.8 allows remote attackers to inject arbitrary web script or HTML via the `prompt` field to the `select_tag` helper.

Active Record allows bypassing of database-query restrictions
Ruby on Rails 3.0.x before 3.0.19, 3.1.x before 3.1.10, and 3.2.x before 3.2.11 does not properly consider differences in parameter handling between the Active Record component and the JSON implementation, which allows remote attackers to bypass intended database-query restrictions and perform NULL checks or trigger missing WHERE clauses via a crafted request, as demonstrated by certain "[nil]" values, a related issue to CVE-2012-2660 and CVE-2012-2694.

Active Record vulnerable to SQL Injection via nested query parameters
The Active Record component in Ruby on Rails 3.0.x before 3.0.13, 3.1.x before 3.1.5, and 3.2.x before 3.2.4 does not properly implement the passing of request data to a where method in an ActiveRecord class, which allows remote attackers to conduct certain SQL injection attacks via nested query parameters that leverage unintended recursion, a related issue to CVE-2012-2695.

activerecord vulnerable to SQL Injection
The Active Record component in Ruby on Rails efore 2.3.15, 3.0.x before 3.0.14, 3.1.x before 3.1.6, and 3.2.x before 3.2.6 does not properly implement the passing of request data to a where method in an ActiveRecord class, which allows remote attackers to conduct certain SQL injection attacks via nested query parameters that leverage improper handling of nested hashes, a related issue to CVE-2012-2661.

Action Pack contains database-query restrictions bypass
`actionpack/lib/action_dispatch/http/request.rb` in Ruby on Rails before 2.3.16, 3.0.x before 3.0.13, 3.1.x before 3.1.5, and 3.2.x before 3.2.4 does not properly consider differences in parameter handling between the Active Record component and the Rack interface, which allows remote attackers to bypass intended database-query restrictions and perform NULL checks via a crafted request, as demonstrated by certain `[nil]` values, a related issue to CVE-2012-2694.

ruby_parser allows local users to overwrite arbitrary files via symlink attack on temporary file with predictable name
The `diff_pp` function in `lib/gauntlet_rubyparser.rb` in the ruby_parser gem 3.1.1 and earlier for Ruby allows local users to overwrite arbitrary files via a symlink attack on a temporary file with a predictable name in `/tmp`.

activesupport Cross-site Scripting vulnerability
Cross-site scripting (XSS) vulnerability in `activesupport/lib/active_support/core_ext/string/output_safety.rb` in Ruby on Rails before 2.3.16, 3.0.x before , 3.1.x before 3.1.8, and 3.2.x before 3.2.8 might allow remote attackers to inject arbitrary web script or HTML via vectors involving a ' (quote) character.

actionpack Cross-site Scripting vulnerability
Cross-site scripting (XSS) vulnerability in `actionpack/lib/action_view/helpers/sanitize_helper.rb` in the `strip_tags` helper in Ruby on Rails before 2.3.16, 3.0.x before 3.0.17, 3.1.x before 3.1.8, and 3.2.x before 3.2.8 allows remote attackers to inject arbitrary web script or HTML via malformed HTML markup.

ActiveRecord vulnerable to modification of protected model attributes
ActiveRecord in Ruby on Rails before 2.3.17, 3.1.x before 3.1.11, and 3.2.x before 3.2.12 allows remote attackers to bypass the `attr_protected` protection mechanism and modify protected model attributes via a crafted request.
