| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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 |
| 2016-09-21 | CVE-2016-7092 | Permissions, Privileges, and Access Controls vulnerability in XEN The get_page_from_l3e function in arch/x86/mm.c in Xen allows local 32-bit PV guest OS administrators to gain host OS privileges via vectors related to L3 recursive pagetables. | 6.8 |
| 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 |
| 2016-06-07 | CVE-2016-5242 | Denial of Service vulnerability in Xen VMID Exhaustion The p2m_teardown function in arch/arm/p2m.c in Xen 4.4.x through 4.6.x allows local guest OS users with access to the driver domain to cause a denial of service (NULL pointer dereference and host OS crash) by creating concurrent domains and holding references to them, related to VMID exhaustion. local xen | 4.7 |
| 2016-06-07 | CVE-2016-4962 | Permissions, Privileges, and Access Controls vulnerability in multiple products The libxl device-handling in Xen 4.6.x and earlier allows local OS guest administrators to cause a denial of service (resource consumption or management facility confusion) or gain host OS privileges by manipulating information in guest controlled areas of xenstore. | 6.8 |
| 2016-05-25 | CVE-2014-3672 | Resource Exhaustion vulnerability in multiple products The qemu implementation in libvirt before 1.3.0 and Xen allows local guest OS users to cause a denial of service (host disk consumption) by writing to stdout or stderr. | 6.5 |
| 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 |
| 2016-04-14 | CVE-2015-8550 | Improper Access Control vulnerability in multiple products Xen, when used on a system providing PV backends, allows local guest OS administrators to cause a denial of service (host OS crash) or gain privileges by writing to memory shared between the frontend and backend, aka a double fetch vulnerability. | 5.7 |
| 2016-04-13 | CVE-2015-8555 | Information Exposure vulnerability in multiple products Xen 4.6.x, 4.5.x, 4.4.x, 4.3.x, and earlier do not initialize x86 FPU stack and XMM registers when XSAVE/XRSTOR are not used to manage guest extended register state, which allows local guest domains to obtain sensitive information from other domains via unspecified vectors. | 5.0 |
