CVE-2019-18222

The ECDSA signature implementation in ecdsa.c in Arm Mbed Crypto 2.1 and Mbed TLS through 2.19.1 does not reduce the blinded scalar before computing the inverse, which allows a local attacker to recover the private key via side-channel attacks...

FreeBSD : Mbed TLS -- Side channel attack on ECDSA (b70b880f-5727-11ea-a2f3-001cc0382b2f)

Janos Follath reports : Our bignum implementation is not constant time/constant trace, so side channel attacks can retrieve the blinded value, factor it as it is smaller than RSA keys and not guaranteed to have only large prime factors, and then, by brute force, recover the key. C Tenable Network...
