1 CVE-2017-8284 264 +Priv 2017-04-26 2017-05-10
6.9
None Local Medium Not required Complete Complete Complete
** 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."
2 CVE-2017-2630 119 Exec Code Overflow 2018-07-27 2018-09-27
6.5
None Remote Low Single system Partial Partial Partial
A stack buffer overflow flaw was found in the Quick Emulator (QEMU) before 2.9 built with the Network Block Device (NBD) client support. The flaw could occur while processing server's response to a 'NBD_OPT_LIST' request. A malicious NBD server could use this issue to crash a remote NBD client resulting in DoS or potentially execute arbitrary code on client host with privileges of the QEMU process.
3 CVE-2016-9381 362 +Priv 2017-01-23 2017-06-30
6.9
None Local Medium Not required Complete Complete Complete
Race condition in QEMU in Xen allows local x86 HVM guest OS administrators to gain privileges by changing certain data on shared rings, aka a "double fetch" vulnerability.
4 CVE-2016-4002 119 DoS Exec Code Overflow Mem. Corr. 2016-04-26 2018-12-01
6.8
None Remote Medium Not required Partial Partial Partial
Buffer overflow in the mipsnet_receive function in hw/net/mipsnet.c in QEMU, when the guest NIC is configured to accept large packets, allows remote attackers to cause a denial of service (memory corruption and QEMU crash) or possibly execute arbitrary code via a packet larger than 1514 bytes.
5 CVE-2016-1714 119 DoS Exec Code Overflow 2016-04-07 2017-11-03
6.9
None Local Medium Not required Complete Complete Complete
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.
6 CVE-2015-8567 399 DoS 2017-04-13 2018-10-30
6.8
None Remote Low Single system None None Complete
Memory leak in net/vmxnet3.c in QEMU allows remote attackers to cause a denial of service (memory consumption).
7 CVE-2015-7512 119 DoS Exec Code Overflow 2016-01-08 2018-01-04
6.8
None Remote Medium Not required Partial Partial Partial
Buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU, when a guest NIC has a larger MTU, allows remote attackers to cause a denial of service (guest OS crash) or execute arbitrary code via a large packet.
8 CVE-2015-3214 119 Exec Code Overflow 2015-08-31 2017-11-03
6.9
None Local Medium Not required Complete Complete Complete
The pit_ioport_read in i8254.c in the Linux kernel before 2.6.33 and QEMU before 2.3.1 does not distinguish between read lengths and write lengths, which might allow guest OS users to execute arbitrary code on the host OS by triggering use of an invalid index.
9 CVE-2014-5263 119 DoS Overflow +Priv Mem. Corr. 2014-08-26 2014-11-18
6.8
None Remote Medium Not required Partial Partial Partial
vmstate_xhci_event in hw/usb/hcd-xhci.c in QEMU 1.6.0 does not terminate the list with the VMSTATE_END_OF_LIST macro, which allows attackers to cause a denial of service (out-of-bounds access, infinite loop, and memory corruption) and possibly gain privileges via unspecified vectors.
10 CVE-2014-3461 119 Exec Code Overflow 2014-11-04 2014-11-05
6.8
None Remote Medium Not required Partial Partial Partial
hw/usb/bus.c in QEMU 1.6.2 allows remote attackers to execute arbitrary code via crafted savevm data, which triggers a heap-based buffer overflow, related to "USB post load checks."
11 CVE-2013-4344 119 Overflow +Priv 2013-10-04 2018-10-30
6.0
None Local High Single system Complete Complete Complete
Buffer overflow in the SCSI implementation in QEMU, as used in Xen, when a SCSI controller has more than 256 attached devices, allows local users to gain privileges via a small transfer buffer in a REPORT LUNS command.
12 CVE-2013-2007 264 2013-05-21 2017-08-28
6.9
None Local Medium Not required Complete Complete Complete
The qemu guest agent in Qemu 1.4.1 and earlier, as used by Xen, when started in daemon mode, uses weak permissions for certain files, which allows local users to read and write to these files.
13 CVE-2011-4111 119 DoS Exec Code Overflow 2014-02-26 2014-02-27
6.8
None Local Network High Not required Complete Complete Complete
Buffer overflow in the ccid_card_vscard_handle_message function in hw/ccid-card-passthru.c in QEMU before 0.15.2 and 1.x before 1.0-rc4 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted VSC_ATR message.
