CVE-2017-13673 1 Qemu 1 Qemu 2023-11-07 4.0 MEDIUM 6.5 MEDIUM
The vga display update in mis-calculated the region for the dirty bitmap snapshot in case split screen mode is used causing a denial of service (assertion failure) in the cpu_physical_memory_snapshot_get_dirty function.
CVE-2016-9602 2 Debian, Qemu 2 Debian Linux, Qemu 2023-11-07 9.0 HIGH 8.8 HIGH
Qemu before version 2.9 is vulnerable to an improper link following when built with the VirtFS. A privileged user inside guest could use this flaw to access host file system beyond the shared folder and potentially escalating their privileges on a host.
CVE-2016-9603 4 Citrix, Debian, Qemu and 1 more 9 Xenserver, Debian Linux, Qemu and 6 more 2023-11-07 9.0 HIGH 9.9 CRITICAL
A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support before 2.9; the issue could occur when a VNC client attempted to update its display after a VGA operation is performed by a guest. A privileged user/process inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process.
CVE-2016-7161 2 Debian, Qemu 2 Debian Linux, Qemu 2023-11-07 10.0 HIGH 9.8 CRITICAL
Heap-based buffer overflow in the .receive callback of xlnx.xps-ethernetlite in QEMU (aka Quick Emulator) allows attackers to execute arbitrary code on the QEMU host via a large ethlite packet.
CVE-2016-7156 2 Debian, Qemu 2 Debian Linux, Qemu 2023-11-07 2.1 LOW 4.4 MEDIUM
The pvscsi_convert_sglist function in hw/scsi/vmw_pvscsi.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) by leveraging an incorrect cast.
CVE-2016-7157 1 Qemu 1 Qemu 2023-11-07 2.1 LOW 4.4 MEDIUM
The (1) mptsas_config_manufacturing_1 and (2) mptsas_config_ioc_0 functions in hw/scsi/mptconfig.c in QEMU (aka Quick Emulator) allow local guest OS administrators to cause a denial of service (QEMU process crash) via vectors involving MPTSAS_CONFIG_PACK.

hw/scsi/vmw_pvscsi.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (out-of-bounds access or infinite loop, and QEMU process crash) via a crafted page count for descriptor rings.
CVE-2016-6888 3 Debian, Qemu, Redhat 5 Debian Linux, Qemu, Enterprise Linux and 2 more 2023-11-07 2.1 LOW 4.4 MEDIUM
Integer overflow in the net_tx_pkt_init function in hw/net/net_tx_pkt.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (QEMU process crash) via the maximum fragmentation count, which triggers an unchecked multiplication and NULL pointer dereference.
CVE-2016-10155 2 Debian, Qemu 2 Debian Linux, Qemu 2023-11-07 4.9 MEDIUM 6.0 MEDIUM
Memory leak in hw/watchdog/wdt_i6300esb.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (host memory consumption and QEMU process crash) via a large number of device unplug operations.
CVE-2015-3456 3 Qemu, Redhat, Xen 5 Qemu, Enterprise Linux, Enterprise Virtualization and 2 more 2023-11-07 7.7 HIGH N/A
The Floppy Disk Controller (FDC) in QEMU, as used in Xen 4.5.x and earlier and KVM, allows local guest users to cause a denial of service (out-of-bounds write and guest crash) or possibly execute arbitrary code via the (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, or other unspecified commands, aka VENOM.
CVE-2014-5263 1 Qemu 1 Qemu 2023-11-07 6.8 MEDIUM N/A
vmstate_xhci_event in hw/usb/hcd-xhci.c in QEMU 1.6.0 does not terminate the list with the VMSTATE_END_OF_LIST macro, which allows attackers to cause a denial of service (out-of-bounds access, infinite loop, and memory corruption) and possibly gain privileges via unspecified vectors.
CVE-2014-3615 5 Canonical, Debian, Opensuse and 2 more 13 Ubuntu Linux, Debian Linux, Opensuse and 10 more 2023-11-07 2.1 LOW N/A
The VGA emulator in QEMU allows local guest users to read host memory by setting the display to a high resolution.
CVE-2013-4535 2 Qemu, Redhat 6 Qemu, Enterprise Linux Desktop, Enterprise Linux Server and 3 more 2023-11-07 7.2 HIGH 8.8 HIGH
The virtqueue_map_sg function in hw/virtio/virtio.c in QEMU before 1.7.2 allows remote attackers to execute arbitrary files via a crafted savevm image, related to virtio-block or virtio-serial read.
CVE-2013-4544 2 Canonical, Qemu 2 Ubuntu Linux, Qemu 2023-11-07 4.9 MEDIUM N/A
hw/net/vmxnet3.c in QEMU 2.0.0-rc0, 1.7.1, and earlier allows local guest users to cause a denial of service or possibly execute arbitrary code via vectors related to (1) RX or (2) TX queue numbers or (3) interrupt indices. NOTE: some of these details are obtained from third party information.
CVE-2011-3346 3 Qemu, Redhat, Xen 3 Qemu, Enterprise Linux, Xen 2023-11-07 4.0 MEDIUM N/A
Buffer overflow in hw/scsi-disk.c in the SCSI subsystem in QEMU before 0.15.2, as used by Xen, might allow local guest users with permission to access the CD-ROM to cause a denial of service (guest crash) via a crafted SAI READ CAPACITY SCSI command. NOTE: this is only a vulnerability when root has manually modified certain permissions or ACLs.
CVE-2008-4539 4 Canonical, Debian, Kvm Qumranet and 1 more 4 Ubuntu Linux, Debian Linux, Kvm and 1 more 2023-11-07 7.2 HIGH N/A
Heap-based buffer overflow in the Cirrus VGA implementation in (1) KVM before kvm-82 and (2) QEMU on Debian GNU/Linux and Ubuntu might allow local users to gain privileges by using the VNC console for a connection, aka the LGD-54XX "bitblt" heap overflow. NOTE: this issue exists because of an incorrect fix for CVE-2007-1320.
CVE-2023-42467 1 Qemu 1 Qemu 2023-11-04 N/A 5.5 MEDIUM
QEMU through 8.0.0 could trigger a division by zero in scsi_disk_reset in hw/scsi/scsi-disk.c because scsi_disk_emulate_mode_select does not prevent s->qdev.blocksize from being 256. This stops QEMU and the guest immediately.
CVE-2018-16872 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2023-05-16 3.5 LOW 5.3 MEDIUM
A flaw was found in qemu 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-2021-3682 3 Debian, Qemu, Redhat 3 Debian Linux, Qemu, Enterprise Linux 2023-03-31 6.0 MEDIUM 8.5 HIGH
A flaw was found in the USB redirector device emulation of QEMU in versions prior to 6.1.0-rc2. It occurs when dropping packets during a bulk transfer from a SPICE client due to the packet queue being full. A malicious SPICE client could use this flaw to make QEMU call free() with faked heap chunk metadata, resulting in a crash of QEMU or potential code execution with the privileges of the QEMU process on the host.
CVE-2022-1050 1 Qemu 1 Qemu 2023-03-15 4.6 MEDIUM 8.8 HIGH
A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device. This flaw allows a crafted guest driver to execute HW commands when shared buffers are not yet allocated, potentially leading to a use-after-free condition.
