Arm Mbed TLS before 2.19.0 and Arm Mbed Crypto before 2.0.0, when
deterministic ECDSA is enabled, use an RNG with insufficient entropy for
blinding, which might allow an attacker to recover a private key via
side-channel attacks if a victim signs the same message many times. (For
Mbed TLS, the fix is also available in versions 2.7.12 and 2.16.3.)
