https://notcve.org/view.php?id=CVE-2015-8803
The ecc_256_modp 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-2015-8805. La función ecc_256_modp en ecc-256.c en Nettle en versiones anteriores a 3.2 no maneja correctamente la propagación del acarreo y produce una salida incorrecta en su implementación de la curva elíptica P-256 NIST, lo que permite a atacantes tener un impacto no especificado a través de vectores desconocidos, una vulnerabilidad diferente a CVE-2015-8805. • http://lists.fedoraproject.org/pipermail/package-announce/2016-February/176807.html http://lists.fedoraproject.org/pipermail/package-announce/2016-February/177229.html http://lists.fedoraproject.org/pipermail/package-announce/2016-February/177473.html http://lists.opensuse.org/opensuse-updates/2016-02/msg00091.html http://lists.opensuse.org/opensuse-updates/2016-02/msg00093.html http://lists.opensuse.org/opensuse-updates/2016-02/msg00100.html http://rhn.redhat.com/errata/RHSA-2016-2582.html http://ww • CWE-254: 7PK - Security Features CWE-310: Cryptographic Issues CWE-358: Improperly Implemented Security Check for Standard •
