Use of a Cryptographic Primitive with a Risky Implementation

CVE-2025-14505

Medium
5.6/10

Summary

The ECDSA implementation of the Elliptic package generates incorrect signatures if an interim value of 'k' (as computed based on step 3.2 of RFC 6979 https://datatracker.ietf.org/doc/html/rfc6979 ) has leading zeros and is susceptible to cryptanalysis, which can lead to secret key exposure. This happens because the byte-length of 'k' is incorrectly computed, resulting in its getting truncated during the computation. Legitimate transactions or communications will be broken as a result. Furthermore, due to the nature of the fault, attackers couldunder certain conditionsderive the secret key if they could get their hands on both a faulty signature generated by a vulnerable version of Elliptic and a correct signature for the same inputs. This issue affects all known versions of Elliptic through 6.6.1.
