Manuel Pégourié-Gonnard reports:

+
The scalar multiplication function in Mbed TLS accepts a random + number generator (RNG) as an optional argument and, if provided, + uses it to protect against some attacks.
+
It is the caller's responsibility to provide a RNG if protection + against side-channel attacks is desired; however two groups of + functions in Mbed TLS itself fail to pass a RNG:
+
+
mbedtls_pk_parse_key() and mbedtls_pk_parse_keyfile()
+
mbedtls_ecp_check_pub_priv() and mbedtls_pk_check_pair()
+
+
When those functions are called, scalar multiplication is computed + without randomisation, a number of old and new attacks apply, + allowing a powerful local attacker to fully recover the private + key.
