Descripción |
|
|
Se ha descubierto una vulnerabilidad de tipo doble liberación de memoria en CUPS 1.3.5. La vulnerabilidad reside en un error en la manera de añadir y eliminar impresoras remotas compartidas mediante IPP. El error se encuentra en la función "process_browse_data()". Un atacante remoto podría causar una denegación de servicio y posiblemente ejecutar código arbitrario mediante el envío de paquetes IPP especialmente diseñados al puerto cupsd (631/udp). |
