| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2017-01-23 | CVE-2016-9381 | Race Condition vulnerability in multiple products Race condition in QEMU in Xen allows local x86 HVM guest OS administrators to gain privileges by changing certain data on shared rings, aka a "double fetch" vulnerability. | 7.5 |
| 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 |
| 2016-08-02 | CVE-2016-6259 | Improper Input Validation vulnerability in multiple products Xen 4.5.x through 4.7.x do not implement Supervisor Mode Access Prevention (SMAP) whitelisting in 32-bit exception and event delivery, which allows local 32-bit PV guest OS kernels to cause a denial of service (hypervisor and VM crash) by triggering a safety check. | 6.2 |
| 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. | 8.8 |
| 2016-06-13 | CVE-2016-5302 | Improper Access Control vulnerability in Citrix Xenserver Citrix XenServer 7.0 before Hotfix XS70E003, when a deployment has been upgraded from an earlier release, might allow remote attackers on the management network to "compromise" a host by leveraging credentials for an Active Directory account. | 9.8 |
| 2016-05-11 | CVE-2016-3712 | Integer Overflow or Wraparound vulnerability in multiple products Integer overflow in the VGA module in QEMU allows local guest OS users to cause a denial of service (out-of-bounds read and QEMU process crash) by editing VGA registers in VBE mode. | 5.5 |
| 2016-05-11 | CVE-2016-3710 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products The VGA module in QEMU improperly performs bounds checking on banked access to video memory, which allows local guest OS administrators to execute arbitrary code on the host by changing access modes after setting the bank register, aka the "Dark Portal" issue. | 8.8 |
