Descriptions

An issue was discovered in Mellium mellium.im/sasl before 0.3.1. When performing SCRAM-based SASL authentication, if the remote end advertises support for channel binding, no random nonce is generated (instead, the nonce is empty). This causes authentication to fail in the best case, but (if paired with a remote end that does not validate the length of the nonce) could lead to insufficient randomness being used during authentication.

Se descubrió un problema en Mellium mellium.im/sasl antes de la versión 0.3.1. Al realizar la autenticación SASL basada en SCRAM, si el extremo remoto anuncia soporte para enlace de canal, no se genera ningún nonce aleatorio (en cambio, el nonce está vacío). Esto hace que la autenticación falle en el mejor de los casos, pero (si se combina con un extremo remoto que no valida la longitud del nonce) podría provocar que se utilice una aleatoriedad insuficiente durante la autenticación.
