CVE-2017-12842 Information

Description

Bitcoin Core before 0.14 allows an attacker to create an ostensibly valid SPV proof for a payment to a victim who uses an SPV wallet even if that payment did not actually occur. Completing the attack would cost more than a million dollars and is relevant mainly only in situations where an autonomous system relies solely on an SPV proof for transactions of a greater dollar amount.
