Minerva timing attack on P-256 in python-ecdsa

python-ecdsa has been found to be subject to a Minerva timing attack on the P-256 curve. Using the ecdsa.SigningKey.signdigest API function and timing signatures an attacker can leak the internal nonce which may allow for private key discovery. Both ECDSA signatures, key generation, and ECDH...

GO-2023-2380 Private key recovery via invalid curve point in github.com/ecies/go/v2

An attacker may be able to recover private keys due to a bug in the ECDH function. The library does not check whether the provided public key is on the curve, which means that an attacker can create a public key that is not on the curve and use it to recover the private key. A workaround is to...
