#	CVE ID	CWE ID	# of Exploits	Vulnerability Type(s)	Publish Date	Update Date	Score	Gained Access Level	Access	Complexity	Authentication	Conf.	Integ.	Avail.
1	CVE-2017-2620	125		Exec Code	2018-07-27	2021-08-04	9.0	None	Remote	Low	???	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	2018-07-03	2021-08-04	9.0	None	Remote	Low	???	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-2016-9637	264		+Priv	2017-02-17	2018-02-08	3.7	None	Local	High	Not required	Partial	Partial	Partial
The (1) ioport_read and (2) ioport_write functions in Xen, when qemu is used as a device model within Xen, might allow local x86 HVM guest OS administrators to gain qemu process privileges via vectors involving an out-of-range ioport access.
4	CVE-2016-9603	119		Exec Code Overflow	2018-07-27	2021-08-04	9.0	None	Remote	Low	???	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.
5	CVE-2016-6259	20		DoS	2016-08-02	2016-08-04	4.9	None	Local	Low	Not required	None	None	Complete
Xen 4.5.x through 4.7.x do not implement Supervisor Mode Access Prevention (SMAP) whitelisting in 32-bit exception and event delivery, which allows local 32-bit PV guest OS kernels to cause a denial of service (hypervisor and VM crash) by triggering a safety check.
6	CVE-2016-6258	284		+Priv	2016-08-02	2017-07-01	7.2	None	Local	Low	Not required	Complete	Complete	Complete
The PV pagetable code in arch/x86/mm.c in Xen 4.7.x and earlier allows local 32-bit PV guest OS administrators to gain host OS privileges by leveraging fast-paths for updating pagetable entries.
7	CVE-2014-4948			DoS +Info	2014-07-22	2017-08-29	6.4	None	Remote	Low	Not required	Partial	None	Partial
Unspecified vulnerability in Citrix XenServer 6.2 Service Pack 1 and earlier allows attackers to cause a denial of service and obtain sensitive information by modifying the guest virtual hard disk (VHD).
8	CVE-2014-4947	119		Overflow	2014-07-22	2017-08-29	10.0	None	Remote	Low	Not required	Complete	Complete	Complete
Buffer overflow in the HVM graphics console support in Citrix XenServer 6.2 Service Pack 1 and earlier has unspecified impact and attack vectors.
