      "value": "Firebird is an open-source relational database management system. In versions prior to 5.0.4, 4.0.7 and 3.0.14, when the server receives an op_crypt_key_callback packet without prior authentication, the port_server_crypt_callback handler is not initialized, resulting in a null pointer dereference and server crash. An unauthenticated attacker who knows only the server's IP and port can exploit this to crash the server. This issue has been fixed in versions 5.0.4, 4.0.7 and 3.0.14."

En versiones anteriores a 5.0.4, 4.0.7 y 3.0.14, cuando el servidor recibe un paquete op_crypt_key_callback sin autenticación previa, el gestor port_server_crypt_callback no se inicializa, lo que resulta en una desreferencia de puntero nulo y un fallo del servidor. Un atacante no autenticado que conoce solo la IP y el puerto del servidor puede explotar esto para provocar un fallo en el servidor. Este problema ha sido solucionado en las versiones 5.0.4, 4.0.7 y 3.0.14."
