Elliptic's verify function omits uniqueness validation

Details

As written in the advisory (Markdown source, shown as plain text).

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.
