Descriptions
The verify function in lib/elliptic/eddsa/index.js in the Elliptic package before 6.5.6 for Node.js omits "sig.S().gte(sig.eddsa.curve.n) || sig.S().isNeg()" validation.
A flaw was found in the Elliptic package. This vulnerability allows attackers to bypass EDDSA signature validation via improper handling of signature values where the S() component of the signature is not properly checked for being non-negative or smaller than the curve order.
