| CVE-2014-0146 | 1 Qemu | 1 Qemu | 2023-02-13 | N/A |
| 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. | ||||
| CVE-2014-0145 | 1 Qemu | 1 Qemu | 2023-02-13 | N/A |
| 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). | ||||
| CVE-2014-0144 | 2 Qemu, Redhat | 9 Qemu, Enterprise Linux Desktop, Enterprise Linux Eus and 6 more | 2023-02-13 | 8.6 High |
| QEMU before 2.0.0 block drivers for CLOOP, QCOW2 version 2 and various other image formats are vulnerable to potential memory corruptions, integer/buffer overflows or crash caused by missing input validations which could allow a remote user to execute arbitrary code on the host with the privileges of the QEMU process. | ||||
| CVE-2014-0143 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2023-02-13 | N/A |
| Multiple integer overflows in the block drivers in QEMU, possibly before 2.0.0, allow local users to cause a denial of service (crash) via a crafted catalog size in (1) the parallels_open function in block/parallels.c or (2) bochs_open function in bochs.c, a large L1 table in the (3) qcow2_snapshot_load_tmp in qcow2-snapshot.c or (4) qcow2_grow_l1_table function in qcow2-cluster.c, (5) a large request in the bdrv_check_byte_request function in block.c and other block drivers, (6) crafted cluster indexes in the get_refcount function in qcow2-refcount.c, or (7) a large number of blocks in the cloop_open function in cloop.c, which trigger buffer overflows, memory corruption, large memory allocations and out-of-bounds read and writes. | ||||
| CVE-2014-0142 | 1 Qemu | 1 Qemu | 2023-02-13 | N/A |
| QEMU, possibly before 2.0.0, allows local users to cause a denial of service (divide-by-zero error and crash) via a zero value in the (1) tracks field to the seek_to_sector function in block/parallels.c or (2) extent_size field in the bochs function in block/bochs.c. | ||||
| CVE-2013-4526 | 1 Qemu | 1 Qemu | 2023-02-13 | N/A |
| Buffer overflow in hw/ide/ahci.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via vectors related to migrating ports. | ||||
| CVE-2012-2652 | 1 Qemu | 1 Qemu | 2023-02-13 | N/A |
| The bdrv_open function in Qemu 1.0 does not properly handle the failure of the mkstemp function, when in snapshot node, which allows local users to overwrite or read arbitrary files via a symlink attack on an unspecified temporary file. | ||||
| CVE-2021-3750 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2023-02-12 | 8.2 High |
| A DMA reentrancy issue was found in the USB EHCI controller emulation of QEMU. EHCI does not verify if the Buffer Pointer overlaps with its MMIO region when it transfers the USB packets. Crafted content may be written to the controller's registers and trigger undesirable actions (such as reset) while the device is still transferring packets. This can ultimately lead to a use-after-free issue. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition, or potentially execute arbitrary code within the context of the QEMU process on the host. This flaw affects QEMU versions before 7.0.0. | ||||
| CVE-2021-3611 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2023-02-12 | 6.5 Medium |
| A stack overflow vulnerability was found in the Intel HD Audio device (intel-hda) of QEMU. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition. The highest threat from this vulnerability is to system availability. This flaw affects QEMU versions prior to 7.0.0. | ||||
| CVE-2021-3507 | 3 Debian, Qemu, Redhat | 3 Debian Linux, Qemu, Enterprise Linux | 2023-02-12 | 6.1 Medium |
| A heap buffer overflow was found in the floppy disk emulator of QEMU up to 6.0.0 (including). It could occur in fdctrl_transfer_handler() in hw/block/fdc.c while processing DMA read data transfers from the floppy drive to the guest system. A privileged guest user could use this flaw to crash the QEMU process on the host resulting in DoS scenario, or potential information leakage from the host memory. | ||||
| CVE-2021-3416 | 4 Debian, Fedoraproject, Qemu and 1 more | 4 Debian Linux, Fedora, Qemu and 1 more | 2023-02-12 | 6.0 Medium |
| A potential stack overflow via infinite loop issue was found in various NIC emulators of QEMU in versions up to and including 5.2.0. The issue occurs in loopback mode of a NIC wherein reentrant DMA checks get bypassed. A guest user/process may use this flaw to consume CPU cycles or crash the QEMU process on the host resulting in DoS scenario. | ||||
| CVE-2020-35517 | 1 Qemu | 1 Qemu | 2023-02-12 | 8.2 High |
| A flaw was found in qemu. A host privilege escalation issue was found in the virtio-fs shared file system daemon where a privileged guest user is able to create a device special file in the shared directory and use it to r/w access host devices. | ||||
| CVE-2019-3812 | 4 Canonical, Fedoraproject, Opensuse and 1 more | 4 Ubuntu Linux, Fedora, Leap and 1 more | 2023-02-12 | N/A |
| QEMU, through version 2.10 and through version 3.1.0, is vulnerable to an out-of-bounds read of up to 128 bytes in the hw/i2c/i2c-ddc.c:i2c_ddc() function. A local attacker with permission to execute i2c commands could exploit this to read stack memory of the qemu process on the host. | ||||
| CVE-2017-7539 | 2 Qemu, Redhat | 4 Qemu, Enterprise Linux, Openstack and 1 more | 2023-02-12 | N/A |
| An assertion-failure flaw was found in Qemu before 2.10.1, in the Network Block Device (NBD) server's initial connection negotiation, where the I/O coroutine was undefined. This could crash the qemu-nbd server if a client sent unexpected data during connection negotiation. A remote user or process could use this flaw to crash the qemu-nbd server resulting in denial of service. | ||||
| CVE-2017-7471 | 1 Qemu | 1 Qemu | 2023-02-12 | 9.0 Critical |
| 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 files on a shared host directory. 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-2017-5931 | 1 Qemu | 1 Qemu | 2023-02-12 | 8.8 High |
| 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. | ||||
| CVE-2017-5857 | 1 Qemu | 1 Qemu | 2023-02-12 | 6.5 Medium |
| 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. | ||||
| CVE-2017-5856 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2023-02-12 | 6.5 Medium |
| Memory leak in the megasas_handle_dcmd function in hw/scsi/megasas.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (host memory consumption) via MegaRAID Firmware Interface (MFI) commands with the sglist size set to a value over 2 Gb. | ||||
| CVE-2017-5667 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2023-02-12 | 6.5 Medium |
| The sdhci_sdma_transfer_multi_blocks function in hw/sd/sdhci.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (out-of-bounds heap access and crash) or execute arbitrary code on the QEMU host via vectors involving the data transfer length. | ||||
| CVE-2017-5579 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2023-02-12 | 6.5 Medium |
| Memory leak in the serial_exit_core function in hw/char/serial.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. | ||||
