Ledger disclosed command-interleaving signing vulnerability class
Ledger disclosed that applications built with affected Ledger Secure SDK releases could accept a new APDU command while an earlier command was awaiting on-screen user review, allowing signing parameters held in application state to be changed after display but before signature generation when an application did not independently validate its state machine.
Ledger disclosed Ethereum clear-signing array-count truncation vulnerability
Ledger disclosed an Ethereum app Generic Transaction Parser flaw in which an attacker-controlled 16-bit array element count was stored in an 8-bit countdown field. For a 257-element array, the device could review only one operation while its signature still authorized the complete transaction.
Ledger disclosed Ethereum swap token-approval substitution vulnerability
Ledger disclosed an Ethereum app flaw in the token-payment path used by the Exchange application during swaps: the path checked the expected address and quantity but not the requested operation type, so a token approval carrying the expected values could pass validation and be signed without being displayed as an approval.
