CVE-2020-12607

An issue was discovered in fastecdsa before 2.1.2. When using the NIST P-256 curve in the ECDSA implementation, the point at infinity is mishandled. This means that for an extreme value in k and s^-1, the signature verification fails even if the signature is correct. This behavior is not solely a...

CVE-2020-12607

CVE-2020-12607 affects the fastecdsa library prior to 2.1.2, where using the NIST P-256 curve in the ECDSA implementation mishandles the point at infinity during signature verification. This can cause verification to fail for an otherwise valid signature when extreme values occur for k and s^-1, ...
