SRAM dump via glitching the firmware update

報告日:December 27, 2018

Using a special glitching hardware an attacker could trick the device processor into Read Protection level 1 which allows readout of RAM. The issue was fixed by not storing sensitive data in RAM during the firmware update.

Fixed in firmware 1.8.0.
