| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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. | 8.8 |
| 2017-05-11 | CVE-2017-8904 | Unspecified vulnerability in XEN 4.8.0/4.8.1 Xen through 4.8.x mishandles the "contains segment descriptors" property during GNTTABOP_transfer (aka guest transfer) operations, which might allow PV guest OS users to execute arbitrary code on the host OS, aka XSA-214. | 8.8 |
| 2017-05-11 | CVE-2017-8903 | Unspecified 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. | 8.8 |
| 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. | 8.2 |
| 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. | 7.8 |
| 2017-01-23 | CVE-2016-9386 | Permissions, Privileges, and Access Controls vulnerability in multiple products The x86 emulator in Xen does not properly treat x86 NULL segments as unusable when accessing memory, which might allow local HVM guest users to gain privileges via vectors involving "unexpected" base/limit values. | 7.8 |
| 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. | 8.8 |
| 2017-01-23 | CVE-2016-9382 | Permissions, Privileges, and Access Controls vulnerability in multiple products Xen 4.0.x through 4.7.x mishandle x86 task switches to VM86 mode, which allows local 32-bit x86 HVM guest OS users to gain privileges or cause a denial of service (guest OS crash) by leveraging a guest operating system that uses hardware task switching and allows a new task to start in VM86 mode. | 7.8 |
| 2017-01-23 | CVE-2016-9380 | Improper Input Validation vulnerability in multiple products The pygrub boot loader emulator in Xen, when nul-delimited output format is requested, allows local pygrub-using guest OS administrators to read or delete arbitrary files on the host via NUL bytes in the bootloader configuration file. | 7.5 |
| 2017-01-23 | CVE-2016-9379 | Improper Input Validation vulnerability in multiple products The pygrub boot loader emulator in Xen, when S-expression output format is requested, allows local pygrub-using guest OS administrators to read or delete arbitrary files on the host via string quotes and S-expressions in the bootloader configuration file. | 7.9 |
