| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2017-01-23 | CVE-2016-9385 | Improper Input Validation vulnerability in multiple products The x86 segment base write emulation functionality in Xen 4.4.x through 4.7.x allows local x86 PV guest OS administrators to cause a denial of service (host crash) by leveraging lack of canonical address checks. | 4.9 |
| 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 |
| 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. | 4.6 |
| 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. | 6.9 |
| 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. | 4.6 |
| 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. | 4.6 |
| 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. | 4.9 |
| 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 |
| 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. | 7.5 |
| 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 |
