Beschreibung:
Ein Sicherheitsproblem in Mozilla Firefox wurde gemeldet, das böswillige Personen ausnutzen können, um Cross-Site-Scripting-Attacken durchzuführen.

Das Problem besteht, da der "jar:"-Protokoll-Handler nicht den MIME-Typ des Inhalts eines Archivs überprüft, der dann im Kontext der bereitstellenden Site ausgeführt wird. Dies kann ausgenutzt werden, um auf Seiten, die Benutzern erlaubt bestimmte Dateien (z.B. .zip, .png, .doc, .odt, .txt) hochzuladen oder auf Seiten mit einem offenen Redirect Cross-Site-Scripting-Attacken durchzuführen.
