Descriptions

A flaw was found in qemu Media Transfer Protocol (MTP) before version 3.1.0. A path traversal in the in usb_mtp_write_data function in hw/usb/dev-mtp.c due to an improper filename sanitization. When the guest device is mounted in read-write mode, this allows to read/write arbitrary files which may lead do DoS scenario OR possibly lead to code execution on the host.

Se ha descubierto un problema en versiones anteriores a la 3.1.0 de QEMU, en el protocolo MTP (Media Transfer Protocol). Un salto de directorio en la función usb_mtp_write_data en hw/usb/dev-mtp.c debido al saneamiento incorrecto de nombres de archivo. Cuando el dispositivo inventado se monta en modo lectura-escritura, esto permite leer/escribir archivos arbitrarios que podrían conducir a un escenario DoS o, posiblemente, conducir a la ejecución de código en el host.
