CVE-2014-1485: Canonical Ubuntu Linux

High severity, CVSS 7.5. EPSS: 3% chance of exploitation in the next 30 days.

The Content Security Policy (CSP) implementation in Mozilla Firefox before 27.0 and SeaMonkey before 2.24 operates on XSLT stylesheets according to style-src directives instead of script-src directives, which might allow remote attackers to execute arbitrary XSLT code by leveraging insufficient style-src restrictions.
