Preserve hardened firmware verification result

This bootloader patch changes how the result of a security check on the currently-running firmware is stored. Previously, the code immediately converted the secure verification result into a plain true/false boolean. Now it keeps the speci…

Harden firmware update validation

This commit changes how Passport's bootloader checks firmware updates. Previously, if the currently-running firmware failed validation, the bootloader would skip verifying the new update's signature and could install it anyway. Now the new…

Lift bounded_message_read to module level

This commit simply moves an existing helper function from inside a method to the top of the same file. The function's behavior and the security limits it enforces are unchanged. There is no security fix or vulnerability introduced.

Bound microSD message read at read time, not via separate stat

This commit fixes a security bug in the Passport hardware wallet's microSD message-signing flow. Previously, the firmware checked a file's size in one operation and then read it in another. Because the microSD card could be swapped between…

Enforce MSG_SIGNING_MAX_LENGTH on microSD message signing

This commit fixes a missing safety limit in the Passport hardware wallet's microSD message-signing feature. Previously, a user could accidentally or maliciously be asked to sign an extremely large file from the microSD card, which could st…

Pass expected_address through QR message signing path

This commit fixes a consistency issue in the QR-code message-signing flow of the Passport hardware wallet. Previously, when signing a message via QR code, the wallet did not pass the user-confirmed address down to the signing code as an ex…
