CVE-2024-48948

elliptic: ECDSA signature verification error may reject legitimate transactions

Published Oct 15, 2024 CVSS 3.1 · 4.8 Medium EPSS < 1% KEV · Not listed
Description
The Elliptic package 6.5.7 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.
