DATE CVE VULNERABILITY TITLE RISK
2017-05-03 CVE-2017-7995 Information Exposure vulnerability in multiple products
Xen PV guest before Xen 4.3 checked access permissions to MMIO ranges only after accessing them, allowing host PCI device space memory reads, leading to information disclosure.

low complexity
xen suse novell CWE-200
1.7
2017-01-26 CVE-2016-9932 Information Exposure vulnerability in XEN
CMPXCHG8B emulation in Xen 3.3.x through 4.7.x on x86 systems allows local HVM guest OS users to obtain sensitive information from host stack memory via a "supposedly-ignored" operand size prefix.
local
low complexity
xen CWE-200
2.1
2017-01-26 CVE-2016-10024 Improper Input Validation vulnerability in multiple products
Xen through 4.8.x allows local x86 PV guest OS kernel administrators to cause a denial of service (host hang or crash) by modifying the instruction stream asynchronously while performing certain kernel operations.

low complexity
xen citrix CWE-20
4.9
2017-01-26 CVE-2016-10013 Permissions, Privileges, and Access Controls vulnerability in XEN
Xen through 4.8.x allows local 64-bit x86 HVM guest OS users to gain privileges by leveraging mishandling of SYSCALL singlestep during emulation.
local
low complexity
xen CWE-264
4.6
2016-10-07 CVE-2016-7777 Race Condition vulnerability in XEN
Xen 4.7.x and earlier does not properly honor CR0.TS and CR0.EM, which allows local x86 HVM guest OS users to read or modify FPU, MMX, or XMM register state information belonging to arbitrary tasks on the guest by modifying an instruction while the hypervisor is preparing to emulate it.
local
xen CWE-362
3.3
2016-09-21 CVE-2016-7094 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in XEN
Buffer overflow in Xen 4.7.x and earlier allows local x86 HVM guest OS administrators on guests running with shadow paging to cause a denial of service via a pagetable update.
local
xen CWE-119
1.5
2016-08-02 CVE-2016-6258 Improper Access Control vulnerability in multiple products
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.
local
low complexity
xen citrix CWE-284
7.2
2016-05-18 CVE-2016-4480 Permissions, Privileges, and Access Controls vulnerability in multiple products
The guest_walk_tables function in arch/x86/mm/guest_walk.c in Xen 4.6.x and earlier does not properly handle the Page Size (PS) page table entry bit at the L4 and L3 page table levels, which might allow local guest OS users to gain privileges via a crafted mapping of memory.

low complexity
oracle xen CWE-264
7.2
2016-04-15 CVE-2016-3961 Improper Input Validation vulnerability in multiple products
Xen and the Linux kernel through 4.5.x do not properly suppress hugetlbfs support in x86 PV guests, which allows local PV guest OS users to cause a denial of service (guest OS crash) by attempting to access a hugetlbfs mapped area.
local
low complexity
canonical xen CWE-20
2.1
2016-04-14 CVE-2015-8554 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in XEN
Buffer overflow in hw/pt-msi.c in Xen 4.6.x and earlier, when using the qemu-xen-traditional (aka qemu-dm) device model, allows local x86 HVM guest administrators to gain privileges by leveraging a system with access to a passed-through MSI-X capable physical PCI device and MSI-X table entries, related to a "write path."
