(RHSA-2014:1102) Important: ror40-rubygem-activerecord security update

Ruby on Rails is a model-view-controller (MVC) framework for web
application development. Active Record implements object-relational mapping
for accessing database entries using objects.

It was discovered that Active Record’s create_with method failed to
properly check attributes passed to it. A remote attacker could possibly
use this flaw to bypass the strong parameter protection and modify
arbitrary model attributes via mass assignment if an application using
Active Record called create_with with untrusted values. (CVE-2014-3514)

All ror40-rubygem-activerecord users are advised to upgrade to these
updated packages, which contain a backported patch to correct this issue.
