filippo.io/edwards25519 is a Go library implementing the edwards25519 elliptic curve with APIs for building cryptographic primitives. In versions 1.1.0 and earlier, MultiScalarMult produces invalid results or undefined behavior if the receiver is not the identity point. If (*Point).MultiScalarMult is called on an initialized point that is not the identity point, it returns an incorrect result. If the method is called on an uninitialized point, the behavior is undefined. In particular, if the receiver is the zero value, MultiScalarMult returns an invalid point that compares Equal to every other point. Note that MultiScalarMult is a rarely used, advanced API. For example, users who depend on filippo.io/edwards25519 only through github.com/go-sql-driver/mysql are not affected. This issue has been fixed in version 1.1.1.

    `(*Point).MultiScalarMult` failed to initialize its receiver. If the method was called on an initialized point that is not the identity point, MultiScalarMult produced an incorrect result. If the method was called on an uninitialized point, the behavior was undefined. In particular, if the receiver was the zero value, MultiScalarMult returned an invalid point that compared Equal to every point. *Note that MultiScalarMult is a rarely used advanced API. For example, if you only depend on `filippo.io/edwards25519` via `github.com/go-sql-driver/mysql`, **you are not affected**. If you were notified of this issue despite not being affected, consider switching to a vulnerability scanner that is more precise and respectful of your attention, like [govulncheck](https://go.dev/doc/tutorial/govulncheck).*
