The DBusServer in libdbus, as used in dbus-daemon, leaks file descriptors when a message exceeds the per-message file descriptor limit. A local attacker with access to the D-Bus system bus or another system service's private AF_UNIX socket could use this to make the system service reach its file descriptor limit, denying service to subsequent D-Bus clients."

El DBusServer en libdbus, como es usado en dbus-daemon, filtra los descriptores de archivo cuando un mensaje excede el l\u00edmite del descriptor de archivo por mensaje. Un atacante local con acceso al bus del sistema D-Bus o al socket AF_UNIX privado de otro servicio del sistema podr\u00eda utilizar esto para hacer que el servicio del sistema alcance su l\u00edmite del descriptor de archivos, negando el servicio a los clientes posteriores de D-Bus"
