|Bugzilla:||921331: CVE-2013-1855 rubygem-actionpack: css_sanitization: XSS vulnerability in sanitize_css|
The MITRE CVE dictionary describes this issue as:
The sanitize_css method 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 \n (newline) characters, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via crafted Cascading Style Sheets (CSS) token sequences.
