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-2017-10918 | 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. | 9.1 |
2017-07-05 | CVE-2017-10915 | Race Condition vulnerability in XEN The shadow-paging feature in Xen through 4.8.x mismanages page references and consequently introduces a race condition, which allows guest OS users to obtain Xen privileges, aka XSA-219. | 9.0 |
