CVE-2023-7345

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, such as asset transfers at incorrect amounts.
