Mozilla Firefox 4.x up to and including 13.0, Firefox ESR 10.x prior to 10.0.6, Thunderbird 5.0 up to and including 13.0, Thunderbird ESR 10.x prior to 10.0.6, and SeaMonkey prior to 2.11 do not properly handle duplicate values in X-Frame-Options headers, which makes it easier for remote malicious users to conduct clickjacking attacks via a FRAME element referencing a web site that produces these duplicate values.
