Using faults for buffer overflow effects

International audienceFault attacks have been developed in the cryptographic com-munity to extract secret information on hardware implemen-tations. They have also been used to bypass security checks during authentication processes for example. Here, we show that they can be exploited to make more damage, taking the control of a machine as buffer overflow attacks do for instance. In this short paper, we demonstrate by using one example that countermeasures against buffer overflow must also be used for software running on embedded processors
