Requiring multiple signatures from different public keys does not mitigate the issue: `ecdsa_verify_list_legacy()` will accept an arbitrary number of such forged signatures. Both the `ecdsautil verify` CLI command and the libecdsautil library are affected. The issue has been fixed in ecdsautils 0.4.1. All older versions of ecdsautils (including versions before the split into a library and a CLI utility) are vulnerable."}, {"lang": "es", "value": "ecdsautils es una peque\u00f1a colecci\u00f3n de programas usados para ECDSA (keygen, sign, verify). \"ecdsa_verify_[prepare_]legacy()\" no comprueba si los valores de la firma \"r\" y \"s\" son distintos de cero. Una firma formada s\u00f3lo por ceros se considera siempre v\u00e1lida, lo que hace trivial la falsificaci\u00f3n de firmas.
