CVE-2013-4529 1 Qemu 1 Qemu 2025-04-12 7.5 HIGH N/A
Buffer overflow in hw/pci/pcie_aer.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a large log_num value in a savevm image.
CVE-2016-4001 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2025-04-12 4.3 MEDIUM 8.6 HIGH
Buffer overflow in the stellaris_enet_receive function in hw/net/stellaris_enet.c in QEMU, when the Stellaris ethernet controller is configured to accept large packets, allows remote attackers to cause a denial of service (QEMU crash) via a large packet.
CVE-2015-8745 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-12 2.1 LOW 5.5 MEDIUM
QEMU (aka Quick Emulator) built with a VMWARE VMXNET3 paravirtual NIC emulator support is vulnerable to crash issue. It could occur while reading Interrupt Mask Registers (IMR). A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the QEMU process instance resulting in DoS.
CVE-2013-4531 1 Qemu 1 Qemu 2025-04-12 7.5 HIGH N/A
Buffer overflow in target-arm/machine.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a negative value in cpreg_vmstate_array_len in a savevm image.
CVE-2015-5158 1 Qemu 1 Qemu 2025-04-12 2.1 LOW 5.5 MEDIUM
Stack-based buffer overflow in hw/scsi/scsi-bus.c in QEMU, when built with SCSI-device emulation support, allows guest OS users with CAP_SYS_RAWIO permissions to cause a denial of service (instance crash) via an invalid opcode in a SCSI command descriptor block.
CVE-2016-4453 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2025-04-12 4.9 MEDIUM 4.4 MEDIUM
The vmsvga_fifo_run function in hw/display/vmware_vga.c in QEMU allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) via a VGA command.
CVE-2016-2391 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2025-04-12 2.1 LOW 5.0 MEDIUM
The ohci_bus_start function in the USB OHCI emulation support (hw/usb/hcd-ohci.c) in QEMU allows local guest OS administrators to cause a denial of service (NULL pointer dereference and QEMU process crash) via vectors related to multiple eof_timers.
CVE-2016-7466 3 Opensuse, Qemu, Redhat 5 Leap, Qemu, Enterprise Linux and 2 more 2025-04-12 1.9 LOW 6.0 MEDIUM
Memory leak in the usb_xhci_exit function in hw/usb/hcd-xhci.c in QEMU (aka Quick Emulator), when the xhci uses msix, allows local guest OS administrators to cause a denial of service (memory consumption and possibly QEMU process crash) by repeatedly unplugging a USB device.
CVE-2016-1922 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-12 2.1 LOW 5.5 MEDIUM
QEMU (aka Quick Emulator) built with the TPR optimization for 32-bit Windows guests support is vulnerable to a null pointer dereference flaw. It occurs while doing I/O port write operations via hmp interface. In that, 'current_cpu' remains null, which leads to the null pointer dereference. A user or process could use this flaw to crash the QEMU instance, resulting in DoS issue.
CVE-2016-7161 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-12 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-2016-8578 3 Debian, Opensuse, Qemu 3 Debian Linux, Leap, Qemu 2025-04-12 2.1 LOW 6.0 MEDIUM
The v9fs_iov_vunmarshal function in fsdev/9p-iov-marshal.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (NULL pointer dereference and QEMU process crash) by sending an empty string parameter to a 9P operation.
