Descriptions

The unity-firefox-extension package could be tricked into dropping a C callback which was still in use, which Firefox would then free, causing Firefox to crash. This could be achieved by adding an action to the launcher and updating it with new callbacks until the libunity-webapps rate limit was hit. Fixed in 3.0.0+14.04.20140416-0ubuntu1.14.04.1 of unity-firefox-extension and in all versions of libunity-webapps by shipping an empty unity-firefox-extension package, thus disabling the extension entirely and invalidating the attack against the libunity-webapps package.

El paquete unity-firefox-extension podría ser engañado para que dejara caer una devolución de llamada C que todavía estaba en uso, que luego Firefox liberaría, causando un bloqueo en Firefox. Esto podría ser alcanzado al agregar una acción al iniciar y actualizar con nuevas devoluciones de llamada hasta que se alcance el límite de frecuencia de libunity-webapps. Se corrigió en versiones 3.0.0+14.04.20140416-0ubuntu1.14.04.1 de unity-firefox-extension y en todas las versiones de libunity-webapps mediante el envío de un paquete de unity-firefox-extension vacío, deshabilitando así la extensión por completo e invalidando el ataque contra el paquete libunity-webapps
