CVE-2015-7576
Published: 16 February 2016
The http_basic_authenticate_with method in actionpack/lib/action_controller/metal/http_authentication.rb in the Basic Authentication implementation in Action Controller in Ruby on Rails before 3.2.22.1, 4.0.x and 4.1.x before 4.1.14.1, 4.2.x before 4.2.5.1, and 5.x before 5.0.0.beta1.1 does not use a constant-time algorithm for verifying credentials, which makes it easier for remote attackers to bypass authentication by measuring timing differences.

seth-arnold | In Oneiric-Saucy, rails package is just for transition; The rails package contains actual code from vivid onward precise_ruby-actionpack-2.3 -- documentation is buggy but doesn't contain an implmentation itself. |
