| 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. | |||||

| The load_multiboot function in hw/i386/multiboot.c in Quick Emulator (aka QEMU) allows local guest OS users to execute arbitrary code on the QEMU host via a mh_load_end_addr value greater than mh_bss_end_addr, which triggers an out-of-bounds read or write memory access. | |||||

| hw/rdma/vmw/pvrdma_cmd.c in QEMU allows attackers to cause a denial of service (NULL pointer dereference or excessive memory allocation) in create_cq_ring or create_qp_rings. | |||||
| CVE-2018-20216 | 2 Canonical, Qemu | 2 Ubuntu Linux, Qemu | 2020-05-12 | 5.0 MEDIUM | 7.5 HIGH |
| QEMU can have an infinite loop in hw/rdma/vmw/pvrdma_dev_ring.c because return values are not checked (and -1 is mishandled). | |||||
| CVE-2013-4535 | 2 Qemu, Redhat | 6 Qemu, Enterprise Linux Desktop, Enterprise Linux Server and 3 more | 2020-02-13 | 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-2020-7211 | 3 Libslirp Project, Microsoft, Qemu | 3 Libslirp, Windows, Qemu | 2020-01-23 | 5.0 MEDIUM | 7.5 HIGH |
| tftp.c in libslirp 4.1.0, as used in QEMU 4.2.0, does not prevent ..\ directory traversal on Windows. | |||||
| CVE-2013-2016 | 3 Debian, Novell, Qemu | 4 Debian Linux, Open Desktop Server, Open Enterprise Server and 1 more | 2020-01-17 | 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-2013-4532 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2020-01-15 | 4.6 MEDIUM | 7.8 HIGH |
| Qemu 1.1.2+dfsg to 2.1+dfsg suffers from a buffer overrun which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process. | |||||
| CVE-2019-20175 | 1 Qemu | 1 Qemu | 2020-01-15 | 5.0 MEDIUM | 7.5 HIGH |
| ** DISPUTED ** An issue was discovered in ide_dma_cb() in hw/ide/core.c in QEMU 2.4.0 through 4.2.0. The guest system can crash the QEMU process in the host system via a special SCSI_IOCTL_SEND_COMMAND. It hits an assertion that implies that the size of successful DMA transfers there must be a multiple of 512 (the size of a sector). NOTE: a member of the QEMU security team disputes the significance of this issue because a "privileged guest user has many ways to cause similar DoS effect, without triggering this assert." | |||||
| CVE-2016-1714 | 3 Oracle, Qemu, Redhat | 3 Linux, Qemu, Openstack | 2019-12-27 | 6.9 MEDIUM | 8.1 HIGH |
| The (1) fw_cfg_write and (2) fw_cfg_read functions in hw/nvram/fw_cfg.c in QEMU before 2.4, when built with the Firmware Configuration device emulation support, allow guest OS users with the CAP_SYS_RAWIO privilege to cause a denial of service (out-of-bounds read or write access and process crash) or possibly execute arbitrary code via an invalid current entry value in a firmware configuration. | |||||
| CVE-2017-15119 | 4 Canonical, Debian, Qemu and 1 more | 4 Ubuntu Linux, Debian Linux, Qemu and 1 more | 2019-10-09 | 5.0 MEDIUM | 8.6 HIGH |
| The Network Block Device (NBD) server in Quick Emulator (QEMU) before 2.11 is vulnerable to a denial of service issue. It could occur if a client sent large option requests, making the server waste CPU time on reading up to 4GB per request. A client could use this flaw to keep the NBD server from serving other requests, resulting in DoS. | |||||
| CVE-2016-9602 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2019-10-09 | 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-2017-15268 | 1 Qemu | 1 Qemu | 2019-10-03 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
| CVE-2017-8284 | 1 Qemu | 1 Qemu | 2019-10-03 | 6.9 MEDIUM | 7.0 HIGH |
| ** DISPUTED ** The disas_insn function in target/i386/translate.c in QEMU before 2.9.0, when TCG mode without hardware acceleration is used, does not limit the instruction size, which allows local users to gain privileges by creating a modified basic block that injects code into a setuid program, as demonstrated by procmail. NOTE: the vendor has stated "this bug does not violate any security guarantees QEMU makes." | |||||
| CVE-2019-15890 | 2 Libslirp Project, Qemu | 2 Libslirp, Qemu | 2019-09-20 | 5.0 MEDIUM | 7.5 HIGH |
| libslirp 4.0.0, as used in QEMU 4.1.0, has a use-after-free in ip_reass in ip_input.c. | |||||
| CVE-2019-12247 | 1 Qemu | 1 Qemu | 2019-05-30 | 5.0 MEDIUM | 7.5 HIGH |
| ** DISPUTED ** QEMU 3.0.0 has an Integer Overflow because the qga/commands*.c files do not check the length of the argument list or the number of environment variables. NOTE: This has been disputed as not exploitable. | |||||
| CVE-2019-5008 | 1 Qemu | 1 Qemu | 2019-05-14 | 5.0 MEDIUM | 7.5 HIGH |
| hw/sparc64/sun4u.c in QEMU 3.1.50 is vulnerable to a NULL pointer dereference, which allows the attacker to cause a denial of service via a device driver. | |||||
| CVE-2014-0143 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2019-04-22 | 4.4 MEDIUM | 7.0 HIGH |
| 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-2016-2538 | 1 Qemu | 1 Qemu | 2018-12-01 | 3.6 LOW | 7.1 HIGH |
| Multiple integer overflows in the USB Net device emulator (hw/usb/dev-network.c) in QEMU before 2.5.1 allow local guest OS administrators to cause a denial of service (QEMU process crash) or obtain sensitive host memory information via a remote NDIS control message packet that is mishandled in the (1) rndis_query_response, (2) rndis_set_response, or (3) usb_net_handle_dataout function. | |||||
| CVE-2017-15124 | 1 Qemu | 1 Qemu | 2018-10-31 | 7.8 HIGH | 7.5 HIGH |
| VNC server implementation in Quick Emulator (QEMU) 2.11.0 and older was found to be vulnerable to an unbounded memory allocation issue, as it did not throttle the framebuffer updates sent to its client. If the client did not consume these updates, VNC server allocates growing memory to hold onto this data. A malicious remote VNC client could use this flaw to cause DoS to the server host. | |||||
| CVE-2014-0145 | 1 Qemu | 1 Qemu | 2017-11-04 | 4.6 MEDIUM | 7.8 HIGH |
| 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). | |||||
