Summary
Ledger Bitcoin app versions 2.1.0 and 2.1.1 contain an address derivation vulnerability that allows attackers to cause incorrect Bitcoin addresses to be displayed by exploiting improper handling of miniscript policies containing the a: fragment. Attackers can craft malicious miniscript policies that cause the device to derive and display incorrect receiving addresses, potentially leading to funds being sent to unintended addresses.
