CVE-2022-29225

Envoy is a cloud-native high-performance proxy. In versions prior to 1.22.1 secompressors accumulate decompressed data into an intermediate buffer before overwriting the body in the decode/encodeBody. This may allow an attacker to zip bomb the decompressor by sending a small highly compressed payload. Maliciously constructed zip files may exhaust system memory and cause a denial of service. Users are advised to upgrade. Users unable to upgrade may consider disabling decompression.

Envoy es un proxy de alto rendimiento nativo de la nube. En versiones anteriores a 1.22.1, los secompresores acumulan los datos descomprimidos en un buffer intermedio antes de sobrescribir el cuerpo en el decode/encodeBody. Esto puede permitir a un atacante bombardear el descompresor mediante el envío de una pequeña carga útil altamente comprimida. Los archivos zip construidos de forma maliciosa pueden agotar la memoria del sistema y causar una denegación de servicio. Es recomendado a usuarios actualizar. Los usuarios que no puedan actualizar pueden considerar deshabilitar la descompresión
