CVE-2025-4565

Any project that uses Protobuf Pure-Python backend to parse untrusted Protocol Buffers data containing an arbitrary number of recursive groups, recursive messages or a series of SGROUP tags can be corrupted by exceeding the Python recursion limit. This can result in a Denial of service by crashing the application with a RecursionError. We recommend upgrading to version =>6.31.1 or beyond commit 17838beda2943d08b8a9d4df5b68f5f04f26d901

Summary		(es) Cualquier proyecto que utilice el backend Protobuf Pure-Python para analizar datos de Protocol Buffers no confiables que contengan un número arbitrario de grupos recursivos, mensajes recursivos o una serie de etiquetas SGROUP puede corromperse al exceder el límite de recursión de Python. Esto puede provocar una denegación de servicio (DSP) que bloquea la aplicación con un RecursionError. Recomendamos actualizar a la versión 6.31.1 o posterior (commit 17838beda2943d08b8a9d4df5b68f5f04f26d901).
