How to fix?

Upgrade Debian:unstable rails to version 2.3.14.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rails package and not the rails package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

The sanitize helper in lib/action_controller/vendor/html-scanner/html/sanitizer.rb in the Action Pack component in Ruby on Rails before 2.3.18, 3.0.x and 3.1.x before 3.1.12, and 3.2.x before 3.2.13 does not properly handle encoded : (colon) characters in URLs, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted scheme name, as demonstrated by including a &#x3a; sequence.
