Descriptions

Envoy is a high-performance edge/middle/service proxy. Envoy crashes in Proxy protocol when using an address type that isn’t supported by the OS. Envoy is susceptible to crashing on a host with IPv6 disabled and a listener config with proxy protocol enabled when it receives a request where the client presents its IPv6 address. It is valid for a client to present its IPv6 address to a target server even though the whole chain is connected via IPv4. This issue has been addressed in released 1.29.1, 1.28.1, 1.27.3, and 1.26.7. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Envoy es un proxy de servicio/intermedio/perimetral de alto rendimiento. Envoy falla en el protocolo Proxy cuando usa un tipo de dirección que no es compatible con el sistema operativo. Envoy es susceptible de fallar en un host con IPv6 deshabilitado y una configuración de escucha con protocolo proxy habilitado cuando recibe una solicitud en la que el cliente presenta su dirección IPv6. Es válido que un cliente presente su dirección IPv6 a un servidor de destino aunque toda la cadena esté conectada a través de IPv4. Este problema se solucionó en las versiones 1.29.1, 1.28.1, 1.27.3 y 1.26.7. Se recomienda a los usuarios que actualicen. No se conocen workarounds para esta vulnerabilidad.
