Descriptions

Mozilla Network Security Services (NSS) before 3.19.1, as used in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, and other products, does not properly perform Elliptical Curve Cryptography (ECC) multiplications, which makes it easier for remote attackers to spoof ECDSA signatures via unspecified vectors.

Mozilla Network Security Services (NSS) anterior a 3.19.1, utilizado en Mozilla Firefox anterior a 39.0, Firefox ESR 31.x anterior a 31.8 y 38.x anterior a 38.1, y otros productos, no realiza correctamente las multiplicaciones Elliptical Curve Cryptography (ECC), lo que facilita a atacantes remotos falsificar firmas ECDSA a través de vectores no especificados.

A flaw was found in the way NSS verified certain ECDSA (Elliptic Curve Digital Signature Algorithm) signatures. Under certain conditions, an attacker could use this flaw to conduct signature forgery attacks.
