Recommendation: Monitor — no exploitation signal at the moment.
When reading DesFire keys, the function that reads the card isn't properly checking the boundaries when copying
internally the data received. This allows a heap based buffer overflow that could lead to a potential Remote Code
Execution on the targeted device. This is especially problematic if you use Default DESFire key.
