| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2015-10-30 | CVE-2015-7969 | Resource Management Errors vulnerability in XEN Multiple memory leaks in Xen 4.0 through 4.6.x allow local guest administrators or domains with certain permission to cause a denial of service (memory consumption) via a large number of "teardowns" of domains with the vcpu pointer array allocated using the (1) XEN_DOMCTL_max_vcpus hypercall or the xenoprofile state vcpu pointer array allocated using the (2) XENOPROF_get_buffer or (3) XENOPROF_set_passive hypercall. | 4.9 |
| 2015-10-30 | CVE-2015-7835 | Improper Input Validation vulnerability in XEN The mod_l2_entry function in arch/x86/mm.c in Xen 3.4 through 4.6.x does not properly validate level 2 page table entries, which allows local PV guest administrators to gain privileges via a crafted superpage mapping. | 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 |
| 2015-10-01 | CVE-2015-7311 | Code vulnerability in XEN libxl in Xen 4.1.x through 4.6.x does not properly handle the readonly flag on disks when using the qemu-xen device model, which allows local guest users to write to a read-only disk image. | 3.6 |
| 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 |
| 2015-07-16 | CVE-2015-3259 | Permissions, Privileges, and Access Controls vulnerability in XEN Stack-based buffer overflow in the xl command line utility in Xen 4.1.x through 4.5.x allows local guest administrators to gain privileges via a long configuration argument. | 6.8 |
| 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 |
| 2015-06-15 | CVE-2015-4163 | Local Denial of Service vulnerability in Xen GNTTABOP_swap_grant_ref in Xen 4.2 through 4.5 does not check the grant table operation version, which allows local guest domains to cause a denial of service (NULL pointer dereference) via a hypercall without a GNTTABOP_setup_table or GNTTABOP_set_version. | 4.9 |
| 2015-06-03 | CVE-2015-4105 | Resource Management Errors vulnerability in XEN Xen 3.3.x through 4.5.x enables logging for PCI MSI-X pass-through error messages, which allows local x86 HVM guests to cause a denial of service (host disk consumption) via certain invalid operations. | 4.9 |
| 2015-06-03 | CVE-2015-4104 | Permissions, Privileges, and Access Controls vulnerability in XEN Xen 3.3.x through 4.5.x does not properly restrict access to PCI MSI mask bits, which allows local x86 HVM guest users to cause a denial of service (unexpected interrupt and host crash) via unspecified vectors. | 7.8 |
