DATE CVE VULNERABILITY TITLE RISK
2017-07-05 CVE-2017-10918 Improper Input Validation vulnerability in XEN
Xen through 4.8.x does not validate memory allocations during certain P2M operations, which allows guest OS users to obtain privileged host OS access, aka XSA-222.

10.0
2017-07-05 CVE-2017-10917 NULL Pointer Dereference vulnerability in XEN
Xen through 4.8.x does not validate the port numbers of polled event channel ports, which allows guest OS users to cause a denial of service (NULL pointer dereference and host OS crash) or possibly obtain sensitive information, aka XSA-221.

9.4
2017-07-05 CVE-2017-10915 Race Condition vulnerability in XEN
The shadow-paging feature in Xen through 4.8.x mismanages page references and consequently introduces a race condition, which allows guest OS users to obtain Xen privileges, aka XSA-219.
network
xen CWE-362
6.8
2017-07-05 CVE-2017-10914 Race Condition vulnerability in XEN
The grant-table feature in Xen through 4.8.x has a race condition leading to a double free, which allows guest OS users to cause a denial of service (memory consumption), or possibly obtain sensitive information or gain privileges, aka XSA-218 bug 2.
network
xen CWE-362
6.8
2017-07-05 CVE-2017-10913 Unspecified vulnerability in XEN
The grant-table feature in Xen through 4.8.x provides false mapping information in certain cases of concurrent unmap calls, which allows backend attackers to obtain sensitive information or gain privileges, aka XSA-218 bug 1.

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
2017-01-23 CVE-2016-9382 Permissions, Privileges, and Access Controls vulnerability in multiple products
Xen 4.0.x through 4.7.x mishandle x86 task switches to VM86 mode, which allows local 32-bit x86 HVM guest OS users to gain privileges or cause a denial of service (guest OS crash) by leveraging a guest operating system that uses hardware task switching and allows a new task to start in VM86 mode.
