| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2017-09-12 | CVE-2017-14317 | Race Condition vulnerability in XEN A domain cleanup issue was discovered in the C xenstore daemon (aka cxenstored) in Xen through 4.9.x. | 4.7 |
| 2017-09-12 | CVE-2017-14316 | Out-of-bounds Read vulnerability in XEN A parameter verification issue was discovered in Xen through 4.9.x. | 7.2 |
| 2017-07-05 | CVE-2017-10923 | Improper Input Validation vulnerability in XEN Xen through 4.8.x does not validate a vCPU array index upon the sending of an SGI, which allows guest OS users to cause a denial of service (hypervisor crash), aka XSA-225. | 5.0 |
| 2017-07-05 | CVE-2017-10922 | Resource Exhaustion vulnerability in XEN The grant-table feature in Xen through 4.8.x mishandles MMIO region grant references, which allows guest OS users to cause a denial of service (loss of grant trackability), aka XSA-224 bug 3. | 5.0 |
| 2017-07-05 | CVE-2017-10921 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in XEN The grant-table feature in Xen through 4.8.x does not ensure sufficient type counts for a GNTMAP_device_map and GNTMAP_host_map mapping, which allows guest OS users to cause a denial of service (count mismanagement and memory corruption) or obtain privileged host OS access, aka XSA-224 bug 2. | 10.0 |
| 2017-07-05 | CVE-2017-10920 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in XEN The grant-table feature in Xen through 4.8.x mishandles a GNTMAP_device_map and GNTMAP_host_map mapping, when followed by only a GNTMAP_host_map unmapping, which allows guest OS users to cause a denial of service (count mismanagement and memory corruption) or obtain privileged host OS access, aka XSA-224 bug 1. | 10.0 |
| 2017-07-05 | CVE-2017-10919 | Denial of Service vulnerability in Xen 'xen/arch/arm/gic.c' Xen through 4.8.x mishandles virtual interrupt injection, which allows guest OS users to cause a denial of service (hypervisor crash), aka XSA-223. | 5.0 |
| 2017-07-05 | CVE-2017-10918 | Improper Input Validation vulnerability in XEN Xen through 4.8.x does not validate memory allocations during certain P2M operations, which allows guest OS users to obtain privileged host OS access, aka XSA-222. | 10.0 |
| 2017-07-05 | CVE-2017-10917 | NULL Pointer Dereference vulnerability in XEN Xen through 4.8.x does not validate the port numbers of polled event channel ports, which allows guest OS users to cause a denial of service (NULL pointer dereference and host OS crash) or possibly obtain sensitive information, aka XSA-221. | 9.4 |
| 2017-07-05 | CVE-2017-10916 | Information Exposure vulnerability in XEN The vCPU context-switch implementation in Xen through 4.8.x improperly interacts with the Memory Protection Extensions (MPX) and Protection Key (PKU) features, which makes it easier for guest OS users to defeat ASLR and other protection mechanisms, aka XSA-220. | 5.0 |
