Descriptions

daemon/gvfsdaemon.c in gvfsd from GNOME gvfs before 1.38.3, 1.40.x before 1.40.2, and 1.41.x before 1.41.3 opened a private D-Bus server socket without configuring an authorization rule. A local attacker could connect to this server socket and issue D-Bus method calls. (Note that the server socket only accepts a single connection, so the attacker would have to discover the server and connect to the socket before its owner does.)

daemon/gvfsdaemon.c in gvfsd from GNOME gvfs anterior 1.38.3, 1.40.x anterior 1.40.2, y 1.41.x anterior 1.41.3 abrió un socket de servidor en D-Bus privado, sin configurar una regla de autorización. Un atacante local podría conectarse a esta toma de servidor y generar llamadas de tipo D-Bus. (tener en cuenta que la toma de servidor solo acepta una única conexione, así el atacante podría tener que descubrir el servidor y conectarse al socket antes que su propio propietario lo haga.
