What is CVE-2019-14359?

A vulnerability has been identified in BC Vault devices concerning the SSD1309 OLED display. The issue arises from the power consumption patterns during the display cycles, which vary based on the number of pixels illuminated. This behavior can potentially allow attackers with physical access and control over the device's USB connection to extract sensitive data by monitoring power consumption at critical moments. For instance, a malware implant in the USB cable could exploit this vulnerability to recover secret PIN data based on the display state. However, this side channel is not relevant when the device is stolen and not actively displaying sensitive information.
