12 Dec 2018 — 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).

26 Nov 2018 — hw/9pfs/cofile.c and hw/9pfs/9p.c in QEMU can modify an fid path while it is being accessed by a second thread, leading to (for example) a use-after-free outcome. hw/9pfs/cofile.c y hw/9pfs/9p.c en QEMU pueden modificar una ruta fid mientras un segundo hilo accede a ella, lo que conduce a, por ejemplo, un uso de memoria previamente liberada. Daniel Shapira and Arash Tohidi discovered that QEMU incorrectly handled NE2000 device emulation. An attacker inside the guest could use this issue to cause QEMU to cra... • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00042.html • CWE-416: Use After Free •
