CVE-2024-45157

An issue was discovered in Mbed TLS before 2.28.9 and 3.x before 3.6.1, in which the user-selected algorithm is not used. Unlike previously documented, enabling MBEDTLS_PSA_HMAC_DRBG_MD_TYPE does not cause the PSA subsystem to use HMAC_DRBG: it uses HMAC_DRBG only when MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG and MBEDTLS_CTR_DRBG_C are disabled.

Se descubrió un problema en Mbed TLS anterior a la versión 2.28.9 y en la versión 3.x anterior a la 3.6.1, en el que no se utiliza el algoritmo seleccionado por el usuario. A diferencia de lo documentado anteriormente, habilitar MBEDTLS_PSA_HMAC_DRBG_MD_TYPE no hace que el subsistema PSA utilice HMAC_DRBG: utiliza HMAC_DRBG solo cuando MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG y MBEDTLS_CTR_DRBG_C están deshabilitados.
