Critical

Published: 23/02/2016(UTC)Translated: 15/06/2026(UTC)NVD NIST

Summary

The ecc_256_modq function in ecc-256.c in Nettle before 3.2 does not properly handle carry propagation, leading to incorrect output in its implementation of the P-256 NIST elliptic curve.

Risk Assessment

Attackers may exploit this vulnerability, potentially leading to unspecified impact on systems using this library.

Recommendation

It is recommended to update the Nettle library to version 3.2 or later to mitigate this vulnerability.

Original NVD description (English source)

The ecc_256_modq function in ecc-256.c in Nettle before 3.2 does not properly handle carry propagation and produces incorrect output in its implementation of the P-256 NIST elliptic curve, which allows attackers to have unspecified impact via unknown vectors, a different vulnerability than CVE-2015-8803.
