The component is: DNS response processing functions: dns_upcall(), getoffset(), dnc_set_answer(). The attack vector is: a specific DNS response packet. The code does not check the \"response data length\" field of individual DNS answers, which may cause out-of-bounds read/write operations, leading to Information leak, Denial-or-Service, or Remote Code Execution, depending on the context."

El componente es: Funciones de procesamiento de respuestas DNS: dns_upcall(), getoffset(), dnc_set_answer(). El vector de ataque es: un paquete de respuesta DNS espec\u00edfico.
