Overview
Affected versions of this package are vulnerable to Improper Input Validation due to the improper validation of user-supplied low-order points during the Diffie-Hellman key exchange process. An attacker can compromise session security by forcing the identity point. Additionally, incorrect point validation in ScalarMult can lead to incorrect results in the isEqual function and verification of whether a point is on the curve.
