Summary

Signature Malleabillity in elliptic

Details

The Elliptic package before version 6.5.3 for Node.js allows ECDSA signature malleability via variations in encoding, leading '\0' bytes, or integer overflows. This could conceivably have a security-relevant impact if an application relied on a single canonical signature.
