CVE-2024-48948 (GCVE-0-2024-48948)
Vulnerability from cvelistv5 – Published: 2024-10-15 00:00 – Updated: 2025-11-25 15:41
VLAI
Summary
The Elliptic package 6.5.7 for Node.js, in its for ECDSA implementation, does not correctly verify valid signatures if the hash contains at least four leading 0 bytes and when the order of the elliptic curve's base point is smaller than the hash, because of an _truncateToN anomaly. This leads to valid signatures being rejected. Legitimate transactions or communications may be incorrectly flagged as invalid.

CVE-2020-28498 (GCVE-0-2020-28498)
Vulnerability from cvelistv5 – Published: 2021-02-02 18:50 – Updated: 2024-09-17 02:00
VLAI
Title
Cryptographic Issues
Summary
The package elliptic before 6.5.4 are vulnerable to Cryptographic Issues via the secp256k1 implementation in elliptic/ec/key.js. There is no check to confirm that the public key point passed into the derive function actually exists on the secp256k1 curve. This results in the potential for the private key used in this implementation to be revealed after a number of ECDH operations are performed.
Severity
6.8 (Medium)

CVE-2020-13822 (GCVE-0-2020-13822)
Vulnerability from cvelistv5 – Published: 2020-06-04 14:01 – Updated: 2024-08-04 12:25
VLAI
Summary
The Elliptic package 6.5.2 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.
Severity
No CVSS data available.
CWE
- n/a
Assigner
