Descriptions

BIRD through 2.0.7 does not provide functionality for password authentication of BGP peers. Because of this, products that use BIRD (which may, for example, include Tigera products in some configurations, as well as products of other vendors) may have been susceptible to route redirection for Denial of Service and/or Information Disclosure. NOTE: a researcher has asserted that the behavior is within Tigera’s area of responsibility; however, Tigera disagrees

** EN DISPUTA ** BIRD versiones hasta 2.0.7, no proporciona una funcionalidad para la autenticación por contraseña de los peers BGP. Debido a esto, los productos que usan BIRD (que pueden, por ejemplo, incluir productos de Tigera en algunas configuraciones, así como productos de otros vendedores) pueden haber sido susceptibles de redireccionamiento de rutas para una Denegación de Servicio y/o Divulgación de Información. NOTA: un investigador ha afirmado que el comportamiento está dentro del área de responsabilidad de Tigera; sin embargo, Tigera no está de acuerdo
