A flaw was found in the Elliptic NodeJS package where it fails to properly verify the leading bit for the R and S values used in the ECDSA signature. This issue may lead to a scenario where an attacker can modify the signature without the Elliptic library being able to properly reject it, causing data confidentiality issues.
