Name of the Vulnerable Software and Affected Versions Ruby on Rails versions 2.x through 2.3.11 Ruby on Rails versions 3.0.x through 3.0.7 Ruby on Rails versions 3.1.x through 3.1.0.rc1

Description The issue is related to the cross-site scripting (XSS) prevention feature, which does not properly handle mutation of safe buffers. This makes it easier for remote attackers to conduct XSS attacks via crafted strings to an application that uses a problematic string method.

Recommendations For Ruby on Rails versions 2.x through 2.3.11, update to version 2.3.12 or later. For Ruby on Rails versions 3.0.x through 3.0.7, update to version 3.0.8 or later. For Ruby on Rails versions 3.1.x through 3.1.0.rc1, update to version 3.1.0.rc2 or later.
