CVE-2020-13822: Integer Overflow
First published: Mon Jun 01 2020(Updated: )
The Elliptic 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.
