Signature Malleabillity in elliptic

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.

Recommendation

Update the elliptic package to the latest compatible version. Followings are version details:

• Affected version(s): < 6.5.3
• Patched version(s): 6.5.3
