## Description

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.
There is a DoS vulnerability in Action Pack digest authentication handling in
Rails.
