|---|---|---|---|---|---|
| CVE-2013-2016 | 3 Debian, Novell, Qemu | 4 Debian Linux, Open Desktop Server, Open Enterprise Server and 1 more | 2020-08-18 | 6.9 MEDIUM | 7.8 HIGH |
| A flaw was found in the way qemu v1.3.0 and later (virtio-rng) validates addresses when guest accesses the config space of a virtio device. If the virtio device has zero/small sized config space, such as virtio-rng, a privileged guest user could use this flaw to access the matching host's qemu address space and thus increase their privileges on the host. | |||||
| CVE-2014-3615 | 5 Canonical, Debian, Opensuse and 2 more | 13 Ubuntu Linux, Debian Linux, Opensuse and 10 more | 2020-08-11 | 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-2013-4344 | 4 Canonical, Opensuse, Qemu and 1 more | 8 Ubuntu Linux, Opensuse, Qemu and 5 more | 2020-08-11 | 7.2 HIGH | N/A |
| Buffer overflow in the SCSI implementation in QEMU, as used in Xen, when a SCSI controller has more than 256 attached devices, allows local users to gain privileges via a small transfer buffer in a REPORT LUNS command. | |||||
| CVE-2019-12068 | 4 Canonical, Debian, Opensuse and 1 more | 4 Ubuntu Linux, Debian Linux, Leap and 1 more | 2020-07-26 | 2.1 LOW | 3.8 LOW |
| In QEMU 1:4.1-1, 1:2.1+dfsg-12+deb8u6, 1:2.8+dfsg-6+deb9u8, 1:3.1+dfsg-8~deb10u1, 1:3.1+dfsg-8+deb10u2, and 1:2.1+dfsg-12+deb8u12 (fixed), when executing script in lsi_execute_script(), the LSI scsi adapter emulator advances 's->dsp' index to read next opcode. This can lead to an infinite loop if the next opcode is empty. Move the existing loop exit after 10k iterations so that it covers no-op opcodes as well. | |||||
| CVE-2020-11869 | 1 Qemu | 1 Qemu | 2020-05-28 | 2.1 LOW | 3.3 LOW |
| An integer overflow was found in QEMU 4.0.1 through 4.2.0 in the way it implemented ATI VGA emulation. This flaw occurs in the ati_2d_blt() routine in hw/display/ati-2d.c while handling MMIO write operations through the ati_mm_write() callback. A malicious guest could abuse this flaw to crash the QEMU process, resulting in a denial of service. | |||||
| CVE-2019-15034 | 1 Qemu | 1 Qemu | 2020-05-28 | 4.4 MEDIUM | 5.8 MEDIUM |
| hw/display/bochs-display.c in QEMU 4.0.0 does not ensure a sufficient PCI config space allocation, leading to a buffer overflow involving the PCIe extended config space. | |||||
| CVE-2016-4441 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2020-05-14 | 2.1 LOW | 6.0 MEDIUM |
| The get_cmd function in hw/scsi/esp.c in the 53C9X Fast SCSI Controller (FSC) support in QEMU does not properly check DMA length, which allows local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) via unspecified vectors, involving an SCSI command. | |||||
| CVE-2016-4439 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2020-05-14 | 4.6 MEDIUM | 6.7 MEDIUM |
| The esp_reg_write function in hw/scsi/esp.c in the 53C9X Fast SCSI Controller (FSC) support in QEMU does not properly check command buffer length, which allows local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) or potentially execute arbitrary code on the QEMU host via unspecified vectors. | |||||
| CVE-2018-16867 | 3 Canonical, Fedoraproject, Qemu | 3 Ubuntu Linux, Fedora, Qemu | 2020-05-14 | 4.4 MEDIUM | 7.8 HIGH |
| 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. | |||||
| CVE-2018-16847 | 2 Canonical, Qemu | 2 Ubuntu Linux, Qemu | 2020-05-14 | 4.6 MEDIUM | 7.8 HIGH |
| An OOB heap buffer r/w access issue was found in the NVM Express Controller emulation in QEMU. It could occur in nvme_cmb_ops routines in nvme device. A guest user/process could use this flaw to crash the QEMU process resulting in DoS or potentially run arbitrary code with privileges of the QEMU process. | |||||
| CVE-2016-4454 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2020-05-14 | 3.6 LOW | 6.0 MEDIUM |
| The vmsvga_fifo_read_raw function in hw/display/vmware_vga.c in QEMU allows local guest OS administrators to obtain sensitive host memory information or cause a denial of service (QEMU process crash) by changing FIFO registers and issuing a VGA command, which triggers an out-of-bounds read. | |||||
| CVE-2016-4453 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2020-05-14 | 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-2020-11102 | 1 Qemu | 1 Qemu | 2020-05-12 | 6.8 MEDIUM | 5.6 MEDIUM |
| hw/net/tulip.c in QEMU 4.2.0 has a buffer overflow during the copying of tx/rx buffers because the frame size is not validated against the r/w data length. | |||||
