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 read access to the statusText property of XMLHttpRequest objects, which allows remote attackers to discover the existence of intranet web servers via cross-origin requests. Cross-site scripting vulnerability in 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 allows user-assisted remote attackers to inject arbitrary web script or HTML via a selection that is added to a document in which the designMode property is enabled. 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 protection mechanisms via UTF-7 encoding. Various other issues were addressed.
