mbedtls_rsa_private() could return the sum of two RSA error codes instead of a valid error code in some rare circumstances: * If rsa_prepare_blinding() returned MBEDTLS_ERR_RSA_RNG_FAILED (indicating a misbehaving or misconfigured RNG). * If the comparison with the public value failed (typically indicating a glitch attack). Make sure not to add two high-level error codes. Signed-off-by: Gilles Peskine <Gilles.Peskine@arm.com>
