| summary: Private key recovery via invalid curve point in github.com/ecies/go/v2 |
| description: |- |
| 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 manually check that the public key is valid by calling the |
| IsOnCurve function from the secp256k1 libraries. |
