CVE-2022-23004

When computing a shared secret or point multiplication on the NIST P-256 curve using a public key with an X coordinate of zero, an error is returned from the library, and an invalid unreduced value is written to the output buffer. This may be leveraged by an attacker to cause an error scenario, resulting in a limited denial of service for an individual user. The scope of impact cannot extend to other components.

Cuando es calculado un secreto compartido o una multiplicación de puntos en la curva P-256 de NIST usando una clave pública con una coordenada X de cero, la biblioteca devuelve un error y es escrito en el búfer de salida un valor inválido no reducido. Esto puede ser aprovechado por un atacante para causar un escenario de error, resultando en una denegación de servicio limitada para un usuario individual. El alcance del impacto no puede extenderse a otros componentes
