- 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.
