Overview
elliptic is a fast elliptic-curve cryptography implementation in plain javascript.

Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature due to a missing signature length check in the EDDSA signature process. An attacker can manipulate the signature by appending or removing zero-valued bytes.
Remediation
Upgrade elliptic to version 6.6.1 or higher.
