Summary
Ledger Live with vulnerable versions of ledgerhq/hw-app-eth prior to 6.34.7 contains an integer parsing vulnerability that allows attackers to manipulate EIP-712 typed data messages by exploiting incorrect hexadecimal field parsing when values contain an odd number of characters. Attackers can obtain signatures on truncated or misinterpreted message values to authorize unintended blockchain transactions.
Risk Assessment
An attacker can trick a user into signing blockchain transactions with incorrect values, potentially leading to loss of funds or unauthorized transfers.
Recommendation
Update Ledger Live and the ledgerhq/hw-app-eth library to version 6.34.7 or later.
