  - A flaw was found in QEMU's Media Transfer Protocol     (MTP). The code opening files in usb_mtp_get_object and     usb_mtp_get_partial_object and directories in     usb_mtp_object_readdir doesn't consider that the     underlying filesystem may have changed since the time     lstat(2) was called in usb_mtp_object_alloc, a     classical TOCTTOU problem. An attacker with write     access to the host filesystem, shared with a guest, can     use this property to navigate the host filesystem in     the context of the QEMU process and read any file the     QEMU process has access to. Access to the filesystem     may be local or via a network share protocol such as     CIFS.(CVE-2018-16872)

  - ** DISPUTED ** An issue was discovered in ide_dma_cb()     in hw/ide/core.c in QEMU 2.4.0 through 4.2.0. The guest     system can crash the QEMU process in the host system     via a special SCSI_IOCTL_SEND_COMMAND. It hits an     assertion that implies that the size of successful DMA     transfers there must be a multiple of 512 (the size of     a sector). NOTE: a member of the QEMU security team     disputes the significance of this issue because a     'privileged guest user has many ways to cause similar     DoS effect, without triggering this     assert.'(CVE-2019-20175)

  - Quick Emulator (QEMU) built with Network Block Device     (NBD) Server support was vulnerable to a null-pointer     dereference issue. The flaw could occur when releasing     a client that was not initialized due to failed     negotiation. A remote user or process could exploit     this flaw to crash the qemu-nbd server (denial of     service).(CVE-2017-9524)

  - Qemu has integer overflows because IOReadHandler and     its associated functions use a signed integer data type     for a size value.(CVE-2018-18438)

  - The Bluetooth subsystem in QEMU mishandles negative     values for length variables, leading to memory     corruption.(CVE-2018-19665)
