| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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 |
| 2017-01-26 | 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. | 4.6 |
| 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 |
| 2016-05-18 | 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 |
| 2016-04-14 | 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 |
| 2016-02-19 | CVE-2016-2270 | Improper Input Validation vulnerability in multiple products Xen 4.6.x and earlier allows local guest administrators to cause a denial of service (host reboot) via vectors related to multiple mappings of MMIO pages with different cachability settings. | 4.6 |
| 2015-12-17 | CVE-2015-8338 | 7PK - Security Features vulnerability in XEN Xen 4.6.x and earlier does not properly enforce limits on page order inputs for the (1) XENMEM_increase_reservation, (2) XENMEM_populate_physmap, (3) XENMEM_exchange, and possibly other HYPERVISOR_memory_op suboperations, which allows ARM guest OS administrators to cause a denial of service (CPU consumption, guest reboot, or watchdog timeout and host reboot) and possibly have unspecified other impact via unknown vectors. | 7.2 |
| 2015-10-30 | CVE-2015-7814 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in XEN Race condition in the relinquish_memory function in arch/arm/domain.c in Xen 4.6.x and earlier allows local domains with partial management control to cause a denial of service (host crash) via vectors involving the destruction of a domain and using XENMEM_decrease_reservation to reduce the memory of the domain. | 4.7 |
