HIGH7.7EPSS 0.41%Signature Malleabillity in elliptic
Published: 7/29/2020Modified: 10/16/2024
Description
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.
Affected packages (2)
- Debian/node-ellipticfrom 0, < 6.5.3~dfsg-1
