Users of Ruby on Rails have been told to update their installations
immediately, following the discovery of a security flaw in the popular
open-source Web application framework.
The Ruby on Rails team members released a patch on Wednesday that they
describe as "mandatory" for all public sites built using recent versions

from 1.1 up to 1.1.4.

The updated version of Rails is available through Ruby's Gems package
management system, or by downloading the package manually from the Rails
