Vulnerability Vulnerable Version

Vulnerability	Vulnerable Version
M Use of a Cryptographic Primitive with a Risky Implementation elliptic is a fast elliptic-curve cryptography implementation in plain javascript. Affected versions of this package are vulnerable to Use of a Cryptographic Primitive with a Risky Implementation due to the incorrect computation of the byte-length of `k` value with leading zeros resulting in its truncation. An attacker can obtain the secret key by analyzing both a faulty signature generated by a vulnerable implementation and a correct signature for the same inputs. Note: There is a distinct but related issue CVE-2024-48948. How to fix Use of a Cryptographic Primitive with a Risky Implementation? There is no fixed version for `elliptic`.	*
C Information Exposure elliptic is a fast elliptic-curve cryptography implementation in plain javascript. Affected versions of this package are vulnerable to Information Exposure due to the `sign` function which allows an attacker to extract the private key from an ECDSA signature by signing a malformed input. A single maliciously crafted signed message can enable full key extraction for any previously known message-signature pair. How to fix Information Exposure? Upgrade `elliptic` to version 6.6.1 or higher.	<6.6.1
