Rails 3.2.7 is in the tree. I hope to get to the older slots during the weekend. Rails 3.1.7 is now also in the tree. Rails 3.0.16 now also in the tree. Thanks, Hans! Please also punt the vulnerable versions. Closing noglsa for ~arch only issue. CVE-2012-3424 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-3424): The decode_credentials method in actionpack/lib/action_controller/metal/http_authentication.rb in Ruby on Rails 3.x 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. |
