CVE-2019-18222

CVE-2019-18222 affects Arm Mbed Crypto 2.1 and Mbed TLS up to 2.19.1: the ECDSA implementation in ecdsa.c does not reduce the blinded scalar before the inverse, enabling local side-channel attacks to recover the private key. Several advisories report upstream fixes (e.g., 2.20.0, 3.0.1) and packa...

Mbed TLS -- Side channel attack on ECDSA

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...

DEBIAN-CVE-2019-16910

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...
