DATE CVE VULNERABILITY TITLE RISK
2013-05-13 CVE-2013-1917 Improper Input Validation vulnerability in XEN
Xen 3.1 through 4.x, when running 64-bit hosts on Intel CPUs, does not clear the NT flag when using an IRET after a SYSENTER instruction, which allows PV guest users to cause a denial of service (hypervisor crash) by triggering a #GP fault, which is not properly handled by another IRET instruction.

xen CWE-20
1.9
2013-04-12 CVE-2013-1920 Permissions, Privileges, and Access Controls vulnerability in XEN
Xen 4.2.x, 4.1.x, and earlier, when the hypervisor is running "under memory pressure" and the Xen Security Module (XSM) is enabled, uses the wrong ordering of operations when extending the per-domain event channel tracking table, which causes a use-after-free and allows local guest kernels to inject arbitrary events and gain privileges via unspecified vectors.

xen CWE-264
4.4
2012-12-13 CVE-2012-6333 Resource Management Errors vulnerability in XEN
Multiple HVM control operations in Xen 3.4 through 4.2 allow local HVM guest OS administrators to cause a denial of service (physical CPU consumption) via a large input.

xen CWE-399
4.7
2012-12-13 CVE-2012-5515 Local Denial of Service vulnerability in Xen 'extent_order' Values
The (1) XENMEM_decrease_reservation, (2) XENMEM_populate_physmap, and (3) XENMEM_exchange hypercalls in Xen 4.2 and earlier allow local guest administrators to cause a denial of service (long loop and hang) via a crafted extent_order value.

2012-12-13 CVE-2012-5514 Local Denial of Service vulnerability in Xen
The guest_physmap_mark_populate_on_demand function in Xen 4.2 and earlier does not properly unlock the subject GFNs when checking if they are in use, which allows local guest HVM administrators to cause a denial of service (hang) via unspecified vectors.

2012-12-13 CVE-2012-5511 Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in XEN
Stack-based buffer overflow in the dirty video RAM tracking functionality in Xen 3.4 through 4.1 allows local HVM guest OS administrators to cause a denial of service (crash) via a large bitmap image.
local
xen CWE-119
4.7
2012-12-13 CVE-2011-3131 Resource Management Errors vulnerability in XEN
Xen 4.1.1 and earlier allows local guest OS kernels with control of a PCI[E] device to cause a denial of service (CPU consumption and host hang) via many crafted DMA requests that are denied by the IOMMU, which triggers a livelock.

4.6
2012-11-21 CVE-2012-4537 Configuration vulnerability in XEN
Xen 3.4 through 4.2, and possibly earlier versions, does not properly synchronize the p2m and m2p tables when the set_p2m_entry function fails, which allows local HVM guest OS administrators to cause a denial of service (memory consumption and assertion failure), aka "Memory mapping failure DoS vulnerability."

xen CWE-16
2.1
2012-11-21 CVE-2012-4535 Resource Management Errors vulnerability in XEN
Xen 3.4 through 4.2, and possibly earlier versions, allows local guest OS administrators to cause a denial of service (Xen infinite loop and physical CPU consumption) by setting a VCPU with an "inappropriate deadline."
local
xen CWE-399
1.9
2012-10-31 CVE-2012-4544 Improper Input Validation vulnerability in XEN
The PV domain builder in Xen 4.2 and earlier does not validate the size of the kernel or ramdisk (1) before or (2) after decompression, which allows local guest administrators to cause a denial of service (domain 0 memory consumption) via a crafted (a) kernel or (b) ramdisk.
