Tyre ovens seem to have helped ferrari lately to achive better temperatures for their tyres for the one lap qualifying.
However, rules quite clearly say that the only tyre heating device allowed are the tyre heating blankets with resistive elements.
Other teams have protested the Ferrari behaviour and fia apparently feels that the Ferrari tyre ovens are legal since they put the whole tyre, with the heating blanket and all, to the oven and hence they are using the blankets to heat the tires and the oven just heats the blankets which is nice and legal.
Either that or they are claiming that the tyre heating ovens are indeed blankets.
