Directory traversal vulnerability in actionpack/lib/action_dispatch/middleware/static.rb in Action Pack in Ruby on Rails 3.x before 3.2.21, 4.0.x before 4.0.12, 4.1.x before 4.1.8, and 4.2.x before 4.2.0.beta4, when serve_static_assets is enabled, allows remote attackers to determine the existence of files outside the application root via vectors involving a \ (backslash) character, a similar issue to CVE-2014-7818.

The str_buf_cat function in string.c in Ruby 1.9.3, 2.0.0, and 2.1 allows context-dependent attackers to cause a denial of service (segmentation fault and crash) via a long string.

Directory traversal vulnerability in actionpack/lib/action_dispatch/middleware/static.rb in Action Pack in Ruby on Rails 3.x before 3.2.20, 4.0.x before 4.0.11, 4.1.x before 4.1.7, and 4.2.x before 4.2.0.beta3, when serve_static_assets is enabled, allows remote attackers to determine the existence of files outside the application root via a /..%2F sequence.

activerecord/lib/active_record/relation/query_methods.rb in Active Record in Ruby on Rails 4.0.x before 4.0.9 and 4.1.x before 4.1.5 allows remote attackers to bypass the strong parameters protection mechanism via crafted input to an application that makes create_with calls.

SQL injection vulnerability in activerecord/lib/active_record/connection_adapters/postgresql/quoting.rb in the PostgreSQL adapter for Active Record in Ruby on Rails 4.x before 4.0.7 and 4.1.x before 4.1.3 allows remote attackers to execute arbitrary SQL commands by leveraging improper range quoting.

SQL injection vulnerability in activerecord/lib/active_record/connection_adapters/postgresql_adapter.rb in the PostgreSQL adapter for Active Record in Ruby on Rails 2.x and 3.x before 3.2.19 allows remote attackers to execute arbitrary SQL commands by leveraging improper bitstring quoting.

Directory traversal vulnerability in actionpack/lib/abstract_controller/base.rb in the implicit-render implementation in Ruby on Rails before 3.2.18, 4.0.x before 4.0.5, and 4.1.x before 4.1.1, when certain route globbing configurations are enabled, allows remote attackers to read arbitrary files via a crafted request.

Multiple cross-site scripting (XSS) vulnerabilities in actionview/lib/action_view/helpers/number_helper.rb in Ruby on Rails before 3.2.17, 4.0.x before 4.0.3, and 4.1.x before 4.1.0.beta2 allow remote attackers to inject arbitrary web script or HTML via the (1) format, (2) negative_format, or (3) units parameter to the (a) number_to_currency, (b) number_to_percentage, or (c) number_to_human helper.

SQL injection vulnerability in activerecord/lib/active_record/connection_adapters/postgresql/cast.rb in Active Record in Ruby on Rails 4.0.x before 4.0.3, and 4.1.0.beta1, when PostgreSQL is used, allows remote attackers to execute "add data" SQL commands via vectors involving \ (backslash) characters that are not properly handled in operations on array columns.

actionpack/lib/action_view/template/text.rb in Action View in Ruby on Rails 3.x before 3.2.17 converts MIME type strings to symbols during use of the :text option to the render method, which allows remote attackers to cause a denial of service (memory consumption) by including these strings in headers.
