| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2016-04-14 | CVE-2015-8554 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in XEN Buffer overflow in hw/pt-msi.c in Xen 4.6.x and earlier, when using the qemu-xen-traditional (aka qemu-dm) device model, allows local x86 HVM guest administrators to gain privileges by leveraging a system with access to a passed-through MSI-X capable physical PCI device and MSI-X table entries, related to a "write path." | 6.6 |
| 2016-04-13 | CVE-2016-3158 | Improper Access Control vulnerability in multiple products The xrstor function in arch/x86/xstate.c in Xen 4.x does not properly handle writes to the hardware FSW.ES bit when running on AMD64 processors, which allows local guest OS users to obtain sensitive register content information from another guest by leveraging pending exception and mask bits. | 1.7 |
| 2016-04-13 | CVE-2015-8552 | Improper Input Validation vulnerability in multiple products The PCI backend driver in Xen, when running on an x86 system and using Linux 3.1.x through 4.3.x as the driver domain, allows local guest administrators to generate a continuous stream of WARN messages and cause a denial of service (disk consumption) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and XEN_PCI_OP_enable_msi operations, aka "Linux pciback missing sanity checks." | 1.7 |
| 2016-02-19 | CVE-2016-2270 | Improper Input Validation vulnerability in multiple products Xen 4.6.x and earlier allows local guest administrators to cause a denial of service (host reboot) via vectors related to multiple mappings of MMIO pages with different cachability settings. | 4.6 |
| 2015-12-17 | CVE-2015-8338 | 7PK - Security Features vulnerability in XEN Xen 4.6.x and earlier does not properly enforce limits on page order inputs for the (1) XENMEM_increase_reservation, (2) XENMEM_populate_physmap, (3) XENMEM_exchange, and possibly other HYPERVISOR_memory_op suboperations, which allows ARM guest OS administrators to cause a denial of service (CPU consumption, guest reboot, or watchdog timeout and host reboot) and possibly have unspecified other impact via unknown vectors. | 7.2 |
| 2015-10-30 | CVE-2015-7814 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in XEN Race condition in the relinquish_memory function in arch/arm/domain.c in Xen 4.6.x and earlier allows local domains with partial management control to cause a denial of service (host crash) via vectors involving the destruction of a domain and using XENMEM_decrease_reservation to reduce the memory of the domain. | 4.7 |
| 2015-08-12 | CVE-2015-5166 | Permissions, Privileges, and Access Controls vulnerability in multiple products Use-after-free vulnerability in QEMU in Xen 4.5.x and earlier does not completely unplug emulated block devices, which allows local HVM guest users to gain privileges by unplugging a block device twice. | 7.2 |
| 2015-06-15 | CVE-2015-4164 | Resource Management Errors vulnerability in XEN The compat_iret function in Xen 3.1 through 4.5 iterates the wrong way through a loop, which allows local 32-bit PV guest administrators to cause a denial of service (large loop and system hang) via a hypercall_iret call with EFLAGS.VM set. | 4.9 |
| 2015-03-18 | CVE-2015-2152 | Permissions, Privileges, and Access Controls vulnerability in multiple products Xen 4.5.x and earlier enables certain default backends when emulating a VGA device for an x86 HVM guest qemu even when the configuration disables them, which allows local guest users to obtain access to the VGA console by (1) setting the DISPLAY environment variable, when compiled with SDL support, or connecting to the VNC server on (2) ::1 or (3) 127.0.0.1, when not compiled with SDL support. | 1.9 |
| 2014-12-09 | CVE-2014-9066 | Code vulnerability in multiple products Xen 4.4.x and earlier, when using a large number of VCPUs, does not properly handle read and write locks, which allows local x86 guest users to cause a denial of service (write denial or NMI watchdog timeout and host crash) via a large number of read requests, a different vulnerability than CVE-2014-9065. | 4.7 |
