Descriptions

Mozilla Network Security Services (NSS) before 3.15.4, as used in Mozilla Firefox before 27.0, Firefox ESR 24.x before 24.3, Thunderbird before 24.3, SeaMonkey before 2.24, and other products, does not properly restrict public values in Diffie-Hellman key exchanges, which makes it easier for remote attackers to bypass cryptographic protection mechanisms in ticket handling by leveraging use of a certain value.

Mozilla Network Security Services (NSS) anterior a 3.15.4, utilizado en Mozilla Firefox anterior a 27.0, Firefox ESR 24.x anterior a 24.3, Thunderbird anterior a 24.3, SeaMonkey anterior a 2.24 y otros productos, no restringe debidamente los valores públicos en el intercambio de claves de Diffie-Hellman, lo que facilita a atacantes remotos evadir mecanismos de protección criptográfica en el manejo de tickets mediante el aprovechamiento de un cierto valor.

It was found that NSS accepted weak Diffie-Hellman Key exchange (DHKE) parameters. This could possibly lead to weak encryption being used in communication between the client and the server.
