Descriptions

bgpd in FRRouting (FRR) before 2.0.2 and 3.x before 3.0.2, as used in Cumulus Linux before 3.4.3 and other products, allows remote attackers to obtain sensitive information via a malformed BGP UPDATE packet from a connected peer, which triggers transmission of up to a few thousand unintended bytes because of a mishandled attribute length, aka RN-690 (CM-18492).

bgpd en FRRouting (FRR) en versiones anteriores a la 2.0.2 y versiones 3.x anteriores a la 3.0.2, tal y como se usa en Cumulus Linux en versiones anteriores a la 3.4.3 y en otros productos, permite que atacantes remotos obtengan información sensible mediante un paquete BGP UPDATE mal formado desde un peer conectado, lo que desencadena la transmisión de hasta miles de bytes no planeados por culpa de la longitud de un atributo gestionado de manera incorrecta. Esta vulnerabilidad también se conoce como RN-690 (CM-18492).
