A stack buffer overflow flaw was found in the Quick Emulator (QEMU) before 2.9 built with the Network Block Device (NBD) client support. The flaw could occur while processing server's response to a 'NBD_OPT_LIST' request. A malicious NBD server could use this issue to crash a remote NBD client resulting in DoS or potentially execute arbitrary code on client host with privileges of the QEMU process.
Se ha encontrado un fallo de desbordamiento de búfer basado en pila en Quick Emulator (QEMU) en versiones anteriores a la 2.9 construida con el soporte de cliente de Network Block Device (NBD). El fallo puede ocurrir durante el procesamiento de la respuesta del servidor a una petición "NBD_OPT_LIST". Un servidor NBD malicioso podría usar este problema para provocar el cierre inesperado de un cliente NBD remoto, resultando en una denegación de servicio (DoS) o potencialmente ejecutando código arbitrario en el host del cliente con privilegios del proceso QEMU.
