CVE-2020-36475

An issue was discovered in Mbed TLS before 2.25.0 (and before 2.16.9 LTS and before 2.7.18 LTS). The calculations performed by mbedtls_mpi_exp_mod are not limited; thus, supplying overly large parameters could lead to denial of service when generating Diffie-Hellman key pairs.

Se ha detectado un problema en Mbed TLS versiones anteriores a 2.25.0 (y versiones anteriores a 2.16.9 LTS y versiones anteriores a 2.7.18 LTS). Los cálculos llevado a cabo por la función mbedtls_mpi_exp_mod no están limitados; por lo tanto, el suministro de parámetros demasiado grandes podría conllevar a una denegación de servicio cuando se generan pares de claves Diffie-Hellman.
