Description
The Style Inspector in Mozilla Firefox before 17.0 and Firefox ESR 10.x before 10.0.11 does not properly restrict the context of HTML markup and Cascading Style Sheets (CSS) token sequences, which allows user-assisted remote attackers to execute arbitrary JavaScript code with chrome privileges via a crafted stylesheet.
