Vulnerability from fkie_nvd - Published: 2026-02-19 23:16 - Updated: 2026-04-15 00:35
Severity ?

Summary
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.

      "value": "filippo.io/edwards25519 es una biblioteca Go que implementa la curva el\u00edptica edwards25519 con API para construir primitivas criptogr\u00e1ficas. En las versiones 1.1.0 y anteriores, MultiScalarMult produce resultados no v\u00e1lidos o comportamiento indefinido si el receptor no es el punto identidad. Si se llama a (*Point).MultiScalarMult en un punto inicializado que no es el punto identidad, devuelve un resultado incorrecto. Si se llama al m\u00e9todo en un punto no inicializado, el comportamiento es indefinido. En particular, si el receptor es el valor cero, MultiScalarMult devuelve un punto no v\u00e1lido que se compara como Igual a cualquier otro punto. Tenga en cuenta que MultiScalarMult es una API avanzada y poco utilizada. Por ejemplo, los usuarios que dependen de filippo.io/edwards25519 solo a trav\u00e9s de github.com/go-sql-driver/mysql no se ven afectados. Este problema ha sido corregido en la versi\u00f3n 1.1.1."
