CVE-2024-42459

In the Elliptic package 6.5.6 for Node.js, EDDSA signature malleability occurs because there is a missing signature length check, and thus zero-valued bytes can be removed or appended.

CVE-2024-42461

In the Elliptic package 6.5.6 for Node.js, ECDSA signature malleability occurs because BER-encoded signatures are allowed.

CVE-2024-42460

In the Elliptic package 6.5.6 for Node.js, ECDSA signature malleability occurs because there is a missing check for whether the leading bit of r and s is zero.

CVE-2024-48949

The Elliptic package 6.5.5 for Node.js for EDDSA implementation does not perform the required check if the signature proof(s) is within the bounds of the order n of the base point of the elliptic curve, leading to signature malleability. Namely, the verify function in lib/elliptic/eddsa/index.js omits sig.S().gte(sig.eddsa.curve.n) || sig.S().isNeg() validation.

This vulnerability could have a security-relevant impact if an application relies on the uniqueness of a signature.

CVE-2024-48948

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.
