Vulnerability Summary

Arm Mbed TLS prior to 2.19.0 and Arm Mbed Crypto prior to 2.0.0, when deterministic ECDSA is enabled, use an RNG with insufficient entropy for blinding, which might allow an malicious user 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.)
