Mozilla Firefox before 3.5.12 and 3.6.x before 3.6.9, Thunderbird
before 3.0.7 and 3.1.x before 3.1.3, and SeaMonkey before 2.0.7 do not
properly restrict use of the type attribute of an OBJECT element to
set a document's charset, which allows remote attackers to bypass
cross-site scripting (XSS) protection mechanisms via UTF-7 encoding.
