DATE CVE VULNERABILITY TITLE RISK
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.

2017-07-05 CVE-2017-10916 Information Exposure vulnerability in XEN
The vCPU context-switch implementation in Xen through 4.8.x improperly interacts with the Memory Protection Extensions (MPX) and Protection Key (PKU) features, which makes it easier for guest OS users to defeat ASLR and other protection mechanisms, aka XSA-220.

5.0
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.

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.

2017-05-11 CVE-2017-8904 Arbitrary Code Execution vulnerability in XEN 4.8.0/4.8.1
Xen through 4.8.x mishandles the "contains segment descriptors" property during GNTTABOP_transfer (aka guest transfer) operations, which might allow PV guest OS users to execute arbitrary code on the host OS, aka XSA-214.
