Upgrade elliptic to version 6.5.6 or higher.
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 improper range validation of the S value in the verify function, allowing the usage of an invalid signature.
Note:
This vulnerability could have a security-relevant impact if an application relies on the uniqueness of a signature.
