CVE-2012-3985 (firefox, linux_enterprise_desktop, linux_enterprise_server, seamonkey, thunderbird, ubuntu_linux)

Mozilla Firefox before 16.0, Thunderbird before 16.0, and SeaMonkey before 2.13 do not properly implement the HTML5 Same Origin Policy, which allows remote attackers to conduct cross-site scripting (XSS) attacks by leveraging initial-origin access after document.domain has been set.
