1 CVE-2018-17962 119 Overflow 2018-10-09 2018-12-01
5.0
 None Remote Low Not required None None Partial
Qemu has a Buffer Overflow in pcnet_receive in hw/net/pcnet.c because an incorrect integer data type is used.
2 CVE-2018-17958 190 Overflow 2018-10-09 2018-11-28
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.
3 CVE-2018-12617 190 Overflow 2018-06-21 2018-11-27
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.
4 CVE-2017-15268 399 2017-10-12 2018-05-31
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.
5 CVE-2017-15119 400 DoS 2018-07-27 2018-09-24
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.
6 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.
7 CVE-2017-10664 19 DoS 2017-08-02 2018-12-01
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.
8 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.
9 CVE-2017-7539 20 DoS 2018-07-26 2018-10-01
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.
10 CVE-2017-6058 125 DoS Overflow 2017-03-20 2017-06-30
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.
11 CVE-2015-8619 787 DoS 2017-04-13 2017-11-03
5.0
 None Remote Low Not required None None Partial
The Human Monitor Interface support in QEMU allows remote attackers to cause a denial of service (out-of-bounds write and application crash).
12 CVE-2015-7295 119 DoS Overflow 2015-11-09 2017-11-03
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.
13 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.
14 CVE-2008-2382 399 DoS 2008-12-24 2018-10-11
5.0
 None Remote Low Not required None None Partial
The protocol_client_msg function in vnc.c in the VNC server in (1) Qemu 0.9.1 and earlier and (2) KVM kvm-79 and earlier allows remote attackers to cause a denial of service (infinite loop) via a certain message.
