DATE CVE VULNERABILITY TITLE RISK
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.

2016-05-11 CVE-2016-3712 Integer Overflow or Wraparound vulnerability in multiple products
Integer overflow in the VGA module in QEMU allows local guest OS users to cause a denial of service (out-of-bounds read and QEMU process crash) by editing VGA registers in VBE mode.
5.5
2016-05-11 CVE-2016-3710 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
The VGA module in QEMU improperly performs bounds checking on banked access to video memory, which allows local guest OS administrators to execute arbitrary code on the host by changing access modes after setting the bank register, aka the "Dark Portal" issue.
7.2
2016-04-13 CVE-2015-8555 Information Exposure vulnerability in multiple products
Xen 4.6.x, 4.5.x, 4.4.x, 4.3.x, and earlier do not initialize x86 FPU stack and XMM registers when XSAVE/XRSTOR are not used to manage guest extended register state, which allows local guest domains to obtain sensitive information from other domains via unspecified vectors.

5.0
2016-01-22 CVE-2016-1571 Code vulnerability in multiple products
The paging_invlpg function in include/asm-x86/paging.h in Xen 3.3.x through 4.6.x, when using shadow mode paging or nested virtualization is enabled, allows local HVM guest users to cause a denial of service (host crash) via a non-canonical guest address in an INVVPID instruction, which triggers a hypervisor bug check.

4.7
2015-06-03 CVE-2015-4106 Incorrect Authorization vulnerability in multiple products
QEMU does not properly restrict write access to the PCI config space for certain PCI pass-through devices, which might allow local x86 HVM guests to gain privileges, cause a denial of service (host crash), obtain sensitive information, or possibly have other unspecified impact via unknown vectors.
