During the retrofit validation process, the firmware doesn't properly check the boundaries while copying some attributesto check. This allows a stack-based buffer overflow that could lead to a potential Remote Code Execution on the targeteddevice

When reading DesFire keys, the function that reads the card isn't properly checking the boundaries when copyinginternally the data received. This allows a heap based buffer overflow that could lead to a potential Remote CodeExecution on the targeted device. This is especially problematic if you use...
