Mozilla Firefox before 15.0 does not properly restrict navigation to the about:newtab page, which allows remote attackers to execute arbitrary JavaScript code with chrome privileges via a crafted web site that triggers creation of a new tab and then a new window.

Security readout for executives and security teams

This is an old Firefox browser flaw fixed before Firefox 15.0. A malicious website could bypass restrictions around the about:newtab page and run JavaScript with elevated browser privileges, increasing the risk of full browser compromise on legacy systems. Exposure is mainly legacy endpoints, kiosks, lab systems, or unmanaged desktops still running Firefox before 15.0 or old distro packages covered by the Ubuntu and SUSE advisories. Treat as urgent only where legacy Firefox remains in use. Modern managed endpoints are unlikely to be exposed, but any confirmed vulnerable browser should be updated or retired because the impact is elevated code execution inside the browser. Mitigation focus: Upgrade Mozilla Firefox to version 15.0 or later.; Apply relevant Ubuntu, SUSE, or openSUSE security updates where packaged Firefox is used.; Retire unsupported systems that cannot run a fixed browser..
