CVE-2011-2197

The cross-site scripting (XSS) prevention feature in Ruby on Rails 2.x
before 2.3.12, 3.0.x before 3.0.8, and 3.1.x before 3.1.0.rc2 does not
properly handle mutation of safe buffers, which makes it easier for remote
attackers to conduct XSS attacks via crafted strings to an application that
uses a problematic string method, as demonstrated by the sub method.
