漏洞描述

In the KeepKey firmware before 7.3.2, the bootloader can be exploited in unusual situations in which the attacker has physical access, convinces the victim to install malicious firmware, or has unspecified other capabilities. lib/board/supervise.c mishandles svhandler_flash_* address range checks. If exploited, any installed malware could persist even after wiping the device and resetting the firmware.

解决建议
