The verify function in the Stark Bank Python ECDSA library (aka starkbank-escada or ecdsa-python) before 2.0.1 fails to check that the signature is non-zero, which allows attackers to forge signatures on arbitrary messages.
The verify function in the Stark Bank Python ECDSA library (aka starkbank-escada or ecdsa-python) before 2.0.1 fails to check that the signature is non-zero, which allows attackers to forge signatures on arbitrary messages.
The verify function in the Stark Bank Python ECDSA library (ecdsa-python) 2.0.0 fails to check that the signature is non-zero, which allows attackers to forge signatures on arbitrary messages.
The `verify` function in the Stark Bank Python ECDSA library (starkbank-ecdsa) 2.0.0 fails to check that the signature is non-zero, which allows attackers to forge signatures on arbitrary messages.
La función verify de la biblioteca ECDSA de Stark Bank Python (también conocida como starkbank-escada o ecdsa-python) anterior a la versión 2.0.1 no comprueba que la firma sea distinta de cero, lo que permite a los atacantes falsificar firmas en mensajes arbitrarios
