https://notcve.org/view.php?id=CVE-2018-16867
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. • http://www.securityfocus.com/bid/106195 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16867 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CGCFIFSIWUREEQQOZDZFBYKWZHXCWBZN https://usn.ubuntu.com/3923-1 https://www.openwall.com/lists/oss-security/2018/12/06/1 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
