| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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. | 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. | 1.5 |
| 2016-06-07 | CVE-2016-4963 | Improper Access Control vulnerability in XEN The libxl device-handling in Xen through 4.6.x allows local guest OS users with access to the driver domain to cause a denial of service (management tool confusion) by manipulating information in the backend directories in xenstore. | 1.9 |
| 2016-06-07 | CVE-2016-4962 | Permissions, Privileges, and Access Controls vulnerability in multiple products The libxl device-handling in Xen 4.6.x and earlier allows local OS guest administrators to cause a denial of service (resource consumption or management facility confusion) or gain host OS privileges by manipulating information in guest controlled areas of xenstore. | 6.8 |
| 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. | 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. | 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." | 6.6 |
| 2016-04-13 | CVE-2016-3159 | Improper Access Control vulnerability in multiple products The fpu_fxrstor function in arch/x86/i387.c in Xen 4.x does not properly handle writes to the hardware FSW.ES bit when running on AMD64 processors, which allows local guest OS users to obtain sensitive register content information from another guest by leveraging pending exception and mask bits. | 1.7 |
| 2016-04-13 | CVE-2016-3158 | Improper Access Control vulnerability in multiple products The xrstor function in arch/x86/xstate.c in Xen 4.x does not properly handle writes to the hardware FSW.ES bit when running on AMD64 processors, which allows local guest OS users to obtain sensitive register content information from another guest by leveraging pending exception and mask bits. | 1.7 |
| 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 |
