interface_release_resource in hw/display/qxl.c in QEMU 4.0.0 has a NULL pointer dereference.
4 CVE-2019-12068 835 Exec Code 2019-09-24 2019-09-26
5.0
 None Remote Low Not required None None Partial
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.

6 CVE-2018-20216 252 2018-12-20 2019-10-02
5.0
 None Remote Low Not required None None Partial
QEMU can have an infinite loop in hw/rdma/vmw/pvrdma_dev_ring.c because return values are not checked (and -1 is mishandled).

8 CVE-2018-20125 476 DoS 2018-12-20 2019-01-17
5.0
 None Remote Low Not required None None Partial

5.0
 None Remote Low Not required None None Partial
Qemu has a Buffer Overflow in rtl8139_do_receive in hw/net/rtl8139.c because an incorrect integer data type is used.
11 CVE-2018-12617 190 Overflow 2018-06-21 2019-05-31
5.0
 None Remote Low Not required None None Partial
qmp_guest_file_read in qga/commands-posix.c and qga/commands-win32.c in qemu-ga (aka QEMU Guest Agent) in QEMU 2.12.50 has an integer overflow causing a g_malloc0() call to trigger a segmentation fault when trying to allocate a large memory chunk. The vulnerability can be exploited by sending a crafted QMP command (including guest-file-read with a large count value) to the agent via the listening socket.
12 CVE-2017-15268 772 2017-10-12 2019-10-02
5.0
 None Remote Low Not required None None Partial
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.
13 CVE-2017-15119 400 DoS 2018-07-27 2019-10-09
5.0
 None Remote Low Not required None None Partial
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.
14 CVE-2017-13711 416 DoS 2017-09-01 2018-04-12
5.0
 None Remote Low Not required None None Partial
Use-after-free vulnerability in the sofree function in slirp/socket.c in QEMU (aka Quick Emulator) allows attackers to cause a denial of service (QEMU instance crash) by leveraging failure to properly clear ifq_so from pending packets.
15 CVE-2017-10664 DoS 2017-08-02 2019-10-02
5.0
 None Remote Low Not required None None Partial
qemu-nbd in QEMU (aka Quick Emulator) does not ignore SIGPIPE, which allows remote attackers to cause a denial of service (daemon crash) by disconnecting during a server-to-client reply attempt.
16 CVE-2017-9524 20 DoS 2017-07-06 2018-01-04
5.0
 None Remote Low Not required None None Partial
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.
17 CVE-2017-7539 20 DoS 2018-07-26 2019-10-09
5.0
 None Remote Low Not required None None Partial
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.

5.0
 None Remote Low Not required None None Partial
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.
19 CVE-2015-8619 787 DoS 2017-04-13 2017-11-03
5.0
 None Remote Low Not required None None Partial

5.0
 None Remote Low Not required None None Partial
hw/virtio/virtio.c in the Virtual Network Device (virtio-net) support in QEMU, when big or mergeable receive buffers are not supported, allows remote attackers to cause a denial of service (guest network consumption) via a flood of jumbo frames on the (1) tuntap or (2) macvtap interface.
21 CVE-2014-7815 264 DoS 2014-11-14 2017-12-27
5.0
 None Remote Low Not required None None Partial
The set_pixel_format function in ui/vnc.c in QEMU allows remote attackers to cause a denial of service (crash) via a small bytes_per_pixel value.
