| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2016-05-25 | CVE-2014-3672 | Resource Exhaustion vulnerability in multiple products The qemu implementation in libvirt before 1.3.0 and Xen allows local guest OS users to cause a denial of service (host disk consumption) by writing to stdout or stderr. | 6.5 |
| 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. | 8.4 |
| 2016-04-19 | CVE-2016-3960 | Integer overflow in the x86 shadow pagetable code in Xen allows local guest OS users to cause a denial of service (host crash) or possibly gain privileges by shadowing a superpage mapping. | 8.8 |
| 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. | 5.5 |
| 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." | 7.5 |
| 2016-04-14 | CVE-2015-8550 | Improper Access Control vulnerability in multiple products Xen, when used on a system providing PV backends, allows local guest OS administrators to cause a denial of service (host OS crash) or gain privileges by writing to memory shared between the frontend and backend, aka a double fetch vulnerability. | 8.2 |
| 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. | 3.8 |
| 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. | 3.8 |
| 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. | 8.6 |
| 2016-04-13 | CVE-2015-8553 | Information Exposure vulnerability in multiple products Xen allows guest OS users to obtain sensitive information from uninitialized locations in host OS kernel memory by not enabling memory and I/O decoding control bits. | 6.5 |
