Descriptions

Mozilla Necko, as used in Thunderbird 3.0.1, SeaMonkey, and other applications, performs DNS prefetching even when the app type is APP_TYPE_MAIL or APP_TYPE_EDITOR, which makes it easier for remote attackers to determine the network location of the application's user by logging DNS requests, as demonstrated by DNS requests triggered by reading text/plain e-mail messages in Thunderbird.

Mozilla Necko usado en Thunderbird v3.0.1, SeaMonkey y otras aplicaciones, realiza una pre-consulta DNS incluso cuando el tipo de aplicación es APP_TYPE_MAIL o APP_TYPE_EDITOR, lo que facilita a atacantes remotos el determinar la localización de red de las aplicaciones de usuario mediante peticiones de loggin DNS, como se demostró mediante las peticiones DNS realizadas con la lectura de los correos en texto plano en Thunderbird.
