1 CVE-2019-12929 78 DoS Exec Code 2019-06-24 2019-07-02
10.0
 None Remote Low Not required Complete Complete Complete
** DISPUTED ** The QMP guest_exec command in QEMU 4.0.0 and earlier is prone to OS command injection, which allows the attacker to achieve code execution, denial of service, or information disclosure by sending a crafted QMP command to the listening server. Note: This has been disputed as a non-issue since QEMU's -qmp interface is meant to be used by trusted users. If one is able to access this interface via a tcp socket open to the internet, then it is an insecure configuration issue.

** DISPUTED ** The QMP migrate command in QEMU version 4.0.0 and earlier is vulnerable to OS command injection, which allows the remote attacker to achieve code execution, denial of service, or information disclosure by sending a crafted QMP command to the listening server. Note: This has been disputed as a non-issue since QEMU's -qmp interface is meant to be used by trusted users. If one is able to access this interface via a tcp socket open to the internet, then it is an insecure configuration issue.
3 CVE-2017-2620 125 Exec Code 2018-07-27 2018-09-07
9.0
 None Remote Low Single system Complete Complete Complete
Quick emulator (QEMU) before 2.8 built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. The issue could occur while copying VGA data in cirrus_bitblt_cputovideo. A privileged user inside guest could use this flaw to crash the QEMU process OR potentially execute arbitrary code on host with privileges of the QEMU process.
4 CVE-2017-2615 125 Exec Code 2018-07-02 2018-09-07
9.0
 None Remote Low Single system Complete Complete Complete
Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA emulator support is vulnerable to an out-of-bounds access issue. It could occur while copying VGA data via bitblt copy in backward mode. A privileged user inside a guest could use this flaw to crash the QEMU process resulting in DoS or potentially execute arbitrary code on the host with privileges of QEMU process on the host.
5 CVE-2016-9603 119 Exec Code Overflow 2018-07-27 2018-09-07
9.0
 None Remote Low Single system Complete Complete Complete
A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support before 2.9; the issue could occur when a VNC client attempted to update its display after a VGA operation is performed by a guest. A privileged user/process inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process.
6 CVE-2016-9602 59 2018-04-26 2019-10-09
9.0
 None Remote Low Single system Complete Complete Complete
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.
7 CVE-2016-7161 119 Exec Code Overflow 2016-10-05 2018-12-01
10.0
 None Remote Low Not required Complete Complete Complete
Heap-based buffer overflow in the .receive callback of xlnx.xps-ethernetlite in QEMU (aka Quick Emulator) allows attackers to execute arbitrary code on the QEMU host via a large ethlite packet.
8 CVE-2016-1568 DoS Exec Code 2016-04-11 2017-11-03
9.3
 None Remote Medium Not required Complete Complete Complete
Use-after-free vulnerability in hw/ide/ahci.c in QEMU, when built with IDE AHCI Emulation support, allows guest OS users to cause a denial of service (instance crash) or possibly execute arbitrary code via an invalid AHCI Native Command Queuing (NCQ) AIO command.
9 CVE-2015-8556 362 2017-03-24 2017-03-27
10.0
 None Remote Low Not required Complete Complete Complete
Local privilege escalation vulnerability in the Gentoo QEMU package before 2.5.0-r1.
10 CVE-2015-6855 264 DoS 2015-11-06 2017-06-30
10.0
 None Remote Low Not required Complete Complete Complete
hw/ide/core.c in QEMU does not properly restrict the commands accepted by an ATAPI device, which allows guest users to cause a denial of service or possibly have unspecified other impact via certain IDE commands, as demonstrated by a WIN_READ_NATIVE_MAX command to an empty drive, which triggers a divide-by-zero error and instance crash.
11 CVE-2012-6075 119 DoS Exec Code Overflow 2013-02-12 2014-04-19
9.3
 None Remote Medium Not required Complete Complete Complete
Buffer overflow in the e1000_receive function in the e1000 device driver (hw/e1000.c) in QEMU 1.3.0-rc2 and other versions, when the SBP and LPE flags are disabled, allows remote attackers to cause a denial of service (guest OS crash) and possibly execute arbitrary guest code via a large packet.
