| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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 |
| 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. | 6.8 |
| 2017-07-05 | CVE-2017-10914 | Race Condition vulnerability in XEN The grant-table feature in Xen through 4.8.x has a race condition leading to a double free, which allows guest OS users to cause a denial of service (memory consumption), or possibly obtain sensitive information or gain privileges, aka XSA-218 bug 2. | 6.8 |
| 2017-07-05 | CVE-2017-10913 | Unspecified vulnerability in XEN The grant-table feature in Xen through 4.8.x provides false mapping information in certain cases of concurrent unmap calls, which allows backend attackers to obtain sensitive information or gain privileges, aka XSA-218 bug 1. | 7.5 |
| 2017-07-05 | CVE-2017-10912 | Privilege Escalation vulnerability in Xen Page Transfer 'xen/arch/x86/mm.c' Xen through 4.8.x mishandles page transfer, which allows guest OS users to obtain privileged host OS access, aka XSA-217. | 10.0 |
| 2017-05-11 | CVE-2017-8905 | Incorrect Calculation vulnerability in XEN Xen through 4.6.x on 64-bit platforms mishandles a failsafe callback, which might allow PV guest OS users to execute arbitrary code on the host OS, aka XSA-215. | 6.8 |
| 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 |
