1 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.
2 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.
3 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.
4 CVE-2016-9602 59 2018-04-26 2018-09-07
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.
5 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.
6 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.
7 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.
8 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.
9 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.
