| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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 |
| 2017-08-24 | CVE-2017-12137 | Classic Buffer Overflow vulnerability in multiple products arch/x86/mm.c in Xen allows local PV guest OS users to gain host OS privileges via vectors related to map_grant_ref. | 7.2 |
| 2017-08-24 | CVE-2017-12134 | Incorrect Calculation vulnerability in multiple products The xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability calculation. | 7.2 |
| 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 |
| 2017-05-11 | CVE-2017-8903 | Arbitrary Code Execution vulnerability in XEN 4.8.0/4.8.1 Xen through 4.8.x on 64-bit platforms mishandles page tables after an IRET hypercall, which might allow PV guest OS users to execute arbitrary code on the host OS, aka XSA-213. | 7.2 |
| 2017-04-04 | CVE-2017-7228 | Improper Validation of Array Index vulnerability in XEN An issue (known as XSA-212) was discovered in Xen, with fixes available for 4.8.x, 4.7.x, 4.6.x, 4.5.x, and 4.4.x. | 7.2 |
| 2017-01-23 | CVE-2016-9383 | Improper Input Validation vulnerability in multiple products Xen, when running on a 64-bit hypervisor, allows local x86 guest OS users to modify arbitrary memory and consequently obtain sensitive information, cause a denial of service (host crash), or execute arbitrary code on the host by leveraging broken emulation of bit test instructions. | 7.2 |
| 2016-09-21 | CVE-2016-7154 | Use After Free vulnerability in XEN Use-after-free vulnerability in the FIFO event channel code in Xen 4.4.x allows local guest OS administrators to cause a denial of service (host crash) and possibly execute arbitrary code or obtain sensitive information via an invalid guest frame number. | 7.2 |
| 2016-09-21 | CVE-2016-7093 | Permissions, Privileges, and Access Controls vulnerability in XEN 4.5.3/4.6.3/4.7.0 Xen 4.5.3, 4.6.3, and 4.7.x allow local HVM guest OS administrators to overwrite hypervisor memory and consequently gain host OS privileges by leveraging mishandling of instruction pointer truncation during emulation. | 7.2 |
| 2016-08-02 | CVE-2016-6258 | Improper Access Control vulnerability in multiple products The PV pagetable code in arch/x86/mm.c in Xen 4.7.x and earlier allows local 32-bit PV guest OS administrators to gain host OS privileges by leveraging fast-paths for updating pagetable entries. | 7.2 |
