2017-02-17 CVE-2016-9637 Permissions, Privileges, and Access Controls vulnerability in Citrix Xenserver
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.

2017-01-26 CVE-2016-10025 NULL Pointer Dereference vulnerability in multiple products
VMFUNC emulation in Xen 4.6.x through 4.8.x on x86 systems using AMD virtualization extensions (aka SVM) allows local HVM guest OS users to cause a denial of service (hypervisor crash) by leveraging a missing NULL pointer check.

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.

4.9
2017-01-23 CVE-2016-9386 Permissions, Privileges, and Access Controls vulnerability in multiple products
The x86 emulator in Xen does not properly treat x86 NULL segments as unusable when accessing memory, which might allow local HVM guest users to gain privileges via vectors involving "unexpected" base/limit values.

4.6
2017-01-23 CVE-2016-9385 Improper Input Validation vulnerability in multiple products
The x86 segment base write emulation functionality in Xen 4.4.x through 4.7.x allows local x86 PV guest OS administrators to cause a denial of service (host crash) by leveraging lack of canonical address checks.

4.9
2017-01-23 CVE-2016-9383 Improper Input Validation vulnerability in multiple products
Xen, when running on a 64-bit hypervisor, allows local x86 guest OS users to modify arbitrary memory and consequently obtain sensitive information, cause a denial of service (host crash), or execute arbitrary code on the host by leveraging broken emulation of bit test instructions.

7.2
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.
