Descriptions

CyaSSL does not check the key usage extension in leaf certificates, which allows remote attackers to spoof servers via a crafted server certificate not authorized for use in an SSL/TLS handshake.

CyaSSL no verifica el uso de la extensión de uso de claves en los certificados de hoja, lo que permite que atacantes remotos suplanten servidores mediante un certificado de servidor manipulado que no está autorizado para su uso en un protocolo handshake SSL/TLS.
