Hi,

The following vulnerability was published for node-elliptic.

CVE-2024-48948[0]:
| 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.
