CVSS v3.1 |
| Integer overflow in hw/virtio/virtio-crypto.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (QEMU process crash) or possibly execute arbitrary code on the host via a crafted virtio-crypto request, which triggers a heap-based buffer overflow. |
| Multiple buffer overflows in QEMU before 1.7.2 and 2.x before 2.0.0, allow local users to cause a denial of service (crash) or possibly execute arbitrary code via a large (1) L1 table in the qcow2_snapshot_load_tmp in the QCOW 2 block driver (block/qcow2-snapshot.c) or (2) uncompressed chunk, (3) chunk length, or (4) number of sectors in the DMG block driver (block/dmg.c). |
| Stack-based buffer overflow in the megasas_ctrl_get_info function in QEMU, when built with SCSI MegaRAID SAS HBA emulation support, allows local guest users to cause a denial of service (QEMU instance crash) via a crafted SCSI controller CTRL_GET_INFO command. |
| The qemu-nbd server in QEMU (aka Quick Emulator), when built with the Network Block Device (NBD) Server support, allows remote attackers to cause a denial of service (segmentation fault and server crash) by leveraging failure to ensure that all initialization occurs before talking to a client in the nbd_negotiate function. |
| 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. |
| Memory leak in the keyboard input event handlers support in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (host memory consumption) by rapidly generating large keyboard events. |
| The qcow2_open function in the (block/qcow2.c) in QEMU before 1.7.2 and 2.x before 2.0.0 allows local users to cause a denial of service (NULL pointer dereference) via a crafted image which causes an error, related to the initialization of the snapshot_offset and nb_snapshots fields. |
| hw/scsi/vmw_pvscsi.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (infinite loop and CPU consumption) via the message ring page count. |
| Memory leak in the virgl_cmd_resource_unref function in hw/display/virtio-gpu-3d.c in QEMU (aka Quick Emulator) allows local guest OS users to cause a denial of service (host memory consumption) via a large number of VIRTIO_GPU_CMD_RESOURCE_UNREF commands sent without detaching the backing storage beforehand. |
| The virgl_cmd_get_capset function in hw/display/virtio-gpu-3d.c in QEMU (aka Quick Emulator) built with Virtio GPU Device emulator support allows local guest OS users to cause a denial of service (out-of-bounds read and process crash) via a VIRTIO_GPU_CMD_GET_CAPSET command with a maximum capabilities size with a value of 0. |
| The dhcp_decode function in slirp/bootp.c in QEMU (aka Quick Emulator) allows local guest OS users to cause a denial of service (out-of-bounds read and QEMU process crash) via a crafted DHCP options string. |
| The virtio_gpu_set_scanout function in QEMU (aka Quick Emulator) built with Virtio GPU Device emulator support allows local guest OS users to cause a denial of service (out-of-bounds read and process crash) via a scanout id in a VIRTIO_GPU_CMD_SET_SCANOUT command larger than num_scanouts. |
| Buffer overflow in NetRxPkt::ehdr_buf in hw/net/net_rx_pkt.c in QEMU (aka Quick Emulator), when the VLANSTRIP feature is enabled on the vmxnet3 device, allows remote attackers to cause a denial of service (out-of-bounds access and QEMU process crash) via vectors related to VLAN stripping. |
| Qemu through 2.10.0 allows remote attackers to cause a memory leak by triggering slow data-channel read operations, related to io/channel-websock.c. |
| Quick Emulator (Qemu) built with the VirtFS, host directory sharing via Plan 9 File System(9pfs) support, is vulnerable to an improper access control issue. It could occur while accessing virtfs metadata files in mapped-file security mode. A guest user could use this flaw to escalate their privileges inside guest. |
| Memory leak in the audio/audio.c in QEMU (aka Quick Emulator) allows remote attackers to cause a denial of service (memory consumption) by repeatedly starting and stopping audio capture. |
| Memory leak in the virtio_gpu_set_scanout function in hw/display/virtio-gpu.c in QEMU (aka Quick Emulator) allows local guest OS users to cause a denial of service (memory consumption) via a large number of "VIRTIO_GPU_CMD_SET_SCANOUT:" commands. |
| The (1) v9fs_create and (2) v9fs_lcreate functions in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allow local guest OS privileged users to cause a denial of service (file descriptor or memory consumption) via vectors related to an already in-use fid. |
| The Virtio Vring implementation in QEMU allows local OS guest users to cause a denial of service (divide-by-zero error and QEMU process crash) by unsetting vring alignment while updating Virtio rings. |
| The ohci_service_ed_list function in hw/usb/hcd-ohci.c in QEMU (aka Quick Emulator) before 2.9.0 allows local guest OS users to cause a denial of service (infinite loop) via vectors involving the number of link endpoint list descriptors, a different vulnerability than CVE-2017-9330. |
