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.

Security readout for executives and security teams

Older Firefox and SeaMonkey versions mishandled a browser security rule called CSP. XSLT content was treated like style content rather than script-controlled content, so a site with weak style-src restrictions could potentially run arbitrary XSLT code. This matters mainly for legacy browser exposure. Exposure is most likely where legacy Firefox before 27.0 or SeaMonkey before 2.24 remains in use, including old Linux packages referenced by vendor advisories. The supplied data does not identify modern supported products as affected. Treat as a legacy exposure cleanup item unless old browsers are still used in production. Prioritize removal or update where browsing untrusted web content is possible. Mitigation focus: Upgrade Firefox to 27.0 or later where still present.; Upgrade SeaMonkey to 2.24 or later where still present.; Apply relevant Mozilla, Ubuntu, openSUSE, or Gentoo security updates..
