GHSA-fc9h-whq2-v747LowCVSS 4.8
Valid ECDSA signatures erroneously rejected in Elliptic
🔗 CVE IDs covered (1)
📋 Description
The Elliptic prior to 6.6.0 for Node.js, in its for ECDSA implementation, does not correctly verify valid signatures if the hash contains at least four leading 0 bytes and when the order of the elliptic curve's base point is smaller than the hash, because of an _truncateToN anomaly. This leads to valid signatures being rejected. Legitimate transactions or communications may be incorrectly flagged as invalid.
