CVE-2025-71417

PocketMine-MP before 5.32.1 fails to validate uniqueness of pack UUIDs in ResourcePackClientResponsePacket STATUS_SEND_PACKS handling, allowing authenticated clients to trigger duplicate pack transmissions. Attackers can send multiple copies of valid pack UUIDs in a single packet to exhaust server memory and cause denial of service.

Summary		(es) PocketMine-MP versiones anteriores a 5.32.1 no valida la unicidad de los UUID de los paquetes en el manejo del ResourcePackClientResponsePacket STATUS_SEND_PACKS, lo que permite a los clientes autenticados desencadenar transmisiones de paquetes duplicados. Los atacantes pueden enviar varias copias de UUID de paquetes válidos en un solo paquete para agotar la memoria del servidor y provocar una denegación de servicio.
