Cross-site scripting (XSS) vulnerability in activesupport/lib/active_support/core_ext/string/output_safety.rb in Ruby on Rails 2.x before 2.3.13, 3.0.x before 3.0.10, and 3.1.x before 3.1.0.rc5 allows remote attackers to inject arbitrary web script or HTML via a malformed Unicode string, related to a "UTF-8 escaping vulnerability."

Cross-site scripting (XSS) vulnerability in the strip_tags helper in actionpack/lib/action_controller/vendor/html-scanner/html/node.rb in Ruby on Rails before 2.3.13, 3.0.x before 3.0.10, and 3.1.x before 3.1.0.rc5 allows remote attackers to inject arbitrary web script or HTML via a tag with an invalid name.

Multiple SQL injection vulnerabilities in the quote_table_name method in the ActiveRecord adapters in activerecord/lib/active_record/connection_adapters/ in Ruby on Rails before 2.3.13, 3.0.x before 3.0.10, and 3.1.x before 3.1.0.rc5 allow remote attackers to execute arbitrary SQL commands via a crafted column name.

The template selection functionality in actionpack/lib/action_view/template/resolver.rb in Ruby on Rails 3.0.x before 3.0.10 and 3.1.x before 3.1.0.rc6 does not properly handle glob characters, which allows remote attackers to render arbitrary views via a crafted URL, related to a "filter skipping vulnerability."

Ruby before 1.8.6-p114 does not reset the random seed upon forking, which makes it easier for context-dependent attackers to predict the values of random numbers by leveraging knowledge of the number sequence obtained in a different child process, a related issue to CVE-2003-0900.

The SecureRandom.random_bytes function in lib/securerandom.rb in Ruby before 1.8.7-p352 and 1.9.x before 1.9.2-p290 relies on PID values for initialization, which makes it easier for context-dependent attackers to predict the result string by leveraging knowledge of random strings obtained in an earlier process with the same PID.

Ruby before 1.8.7-p352 does not reset the random seed upon forking, which makes it easier for context-dependent attackers to predict the values of random numbers by leveraging knowledge of the number sequence obtained in a different child process, a related issue to CVE-2003-0900. NOTE: this issue exists because of a regression during Ruby 1.8.6 development.

The cross-site scripting (XSS) prevention feature in Ruby on Rails 2.x before 2.3.12, 3.0.x before 3.0.8, and 3.1.x before 3.1.0.rc2 does not properly handle mutation of safe buffers, which makes it easier for remote attackers to conduct XSS attacks via crafted strings to an application that uses a problematic string method, as demonstrated by the sub method.

The sqlite3-ruby gem in the rubygem-sqlite3 package before 1.2.4-0.5.1 in SUSE Linux Enterprise (SLE) 11 SP1 uses weak permissions for unspecified files, which allows local users to gain privileges via unknown vectors.

Use-after-free vulnerability in Google Chrome before 11.0.696.57 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to the ruby element and Cascading Style Sheets (CSS) token sequences.

The VpMemAlloc function in bigdecimal.c in the BigDecimal class in Ruby 1.9.2-p136 and earlier, as used on Apple Mac OS X before 10.6.7 and other platforms, does not properly allocate memory, which allows context-dependent attackers to execute arbitrary code or cause a denial of service (application crash) via vectors involving creation of a large BigDecimal value within a 64-bit process, related to an "integer truncation issue."

The safe-level feature in Ruby 1.8.6 through 1.8.6-420, 1.8.7 through 1.8.7-330, and 1.8.8dev allows context-dependent attackers to modify strings via the Exception#to_s method, as demonstrated by changing an intended pathname.

The FileUtils.remove_entry_secure method in Ruby 1.8.6 through 1.8.6-420, 1.8.7 through 1.8.7-330, 1.8.8dev, 1.9.1 through 1.9.1-430, 1.9.2 through 1.9.2-136, and 1.9.3dev allows local users to delete arbitrary files via a symlink attack.

actionpack/lib/action_view/template/resolver.rb in Ruby on Rails 3.0.x before 3.0.4, when a case-insensitive filesystem is used, does not properly implement filters associated with the list of available templates, which allows remote attackers to bypass intended access restrictions via an action name that uses an unintended case for alphabetic characters.

Ruby on Rails 3.0.x before 3.0.4 does not ensure that arguments to the limit function specify integer values, which makes it easier for remote attackers to conduct SQL injection attacks via a non-numeric argument.

Ruby on Rails 2.1.x, 2.2.x, and 2.3.x before 2.3.11, and 3.x before 3.0.4, does not properly validate HTTP requests that contain an X-Requested-With header, which makes it easier for remote attackers to conduct cross-site request forgery (CSRF) attacks via forged (1) AJAX or (2) API requests that leverage "combinations of browser plugins and HTTP redirects," a related issue to CVE-2011-0696.

Multiple cross-site scripting (XSS) vulnerabilities in the mail_to helper in Ruby on Rails before 2.3.11, and 3.x before 3.0.4, when javascript encoding is used, allow remote attackers to inject arbitrary web script or HTML via a crafted (1) name or (2) email value.

The deliver function in the sendmail delivery agent (lib/mail/network/delivery_methods/sendmail.rb) in Ruby Mail gem 2.2.14 and earlier allows remote attackers to execute arbitrary commands via shell metacharacters in an e-mail address.

Ruby Version Manager (RVM) before 1.2.1 writes file contents to a terminal without sanitizing non-printable characters, which might allow remote attackers to execute arbitrary commands via a crafted file, related to an "escape sequence injection vulnerability." NOTE: some of these details are obtained from third party information.

Ruby on Rails 2.3.9 and 3.0.0 does not properly handle nested attributes, which allows remote attackers to modify arbitrary records by changing the names of parameters for form inputs.
