A Cryptographic Near Miss

Go 1.20.2 fixed a small vulnerability in the crypto/elliptic package. The impact was minor, to the point that I don't think any application was impacted, but the issue was interesting to look at as a near-miss, and to learn from. Fundamentally, a scalar multiplication function was returning the...

Incorrect ECC Calculation

Go is vulnerable to Incorrect ECC Calculation in its crypto/elliptic package. The vulnerability is due to defects in the functions ScalarBaseMult and ScalarMult in p256asm.go and p256ordinv.go files while performing P256 Curve implementation of Elliptic-curve cryptography ECC. The functions do no...
