DATE CVE VULNERABILITY TITLE RISK
2013-10-17 CVE-2013-4371 Resource Management Errors vulnerability in XEN
Use-after-free vulnerability in the libxl_list_cpupool function in the libxl toolstack library in Xen 4.2.x and 4.3.x, when running "under memory pressure," returns the original pointer when the realloc function fails, which allows local users to cause a denial of service (heap corruption and crash) and possibly execute arbitrary code via unspecified vectors.

4.4
2013-10-17 CVE-2013-4370 Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in XEN
The ocaml binding for the xc_vcpu_getaffinity function in Xen 4.2.x and 4.3.x frees certain memory that may still be intended for use, which allows local users to cause a denial of service (heap corruption and crash) and possibly execute arbitrary code via unspecified vectors that trigger a (1) use-after-free or (2) double free.

2013-10-17 CVE-2013-4369 NULL pointer Dereference Remote Denial of Service vulnerability in Xen
The xlu_vif_parse_rate function in the libxlu library in Xen 4.2.x and 4.3.x allows local users to cause a denial of service (NULL pointer dereference) by using the "@" character as the VIF rate configuration.

2013-10-17 CVE-2013-4368 Information Exposure vulnerability in XEN
The outs instruction emulation in Xen 3.1.x, 4.2.x, 4.3.x, and earlier, when using FS: or GS: segment override, uses an uninitialized variable as a segment base, which allows local 64-bit PV guests to obtain sensitive information (hypervisor stack content) via unspecified vectors related to stale data in a segment register.

1.9
2013-10-01 CVE-2013-4361 Information Exposure vulnerability in XEN
The fbld instruction emulation in Xen 3.3.x through 4.3.x does not use the correct variable for the source effective address, which allows local HVM guests to obtain hypervisor stack information by reading the values used by the instruction.

2.1
2013-09-30 CVE-2013-1442 Information Exposure vulnerability in XEN
Xen 4.0 through 4.3.x, when using AVX or LWP capable CPUs, does not properly clear previous data from registers when using an XSAVE or XRSTOR to extend the state components of a saved or restored vCPU after touching other restored extended registers, which allows local guest OSes to obtain sensitive information by reading the registers.

high complexity
xen CWE-200
1.2
2013-09-12 CVE-2013-4329 Permissions, Privileges, and Access Controls vulnerability in XEN
The xenlight library (libxl) in Xen 4.0.x through 4.2.x, when IOMMU is disabled, provides access to a busmastering-capable PCI passthrough device before the IOMMU setup is complete, which allows local HVM guest domains to gain privileges or cause a denial of service via a DMA instruction.

xen CWE-264
6.5
2013-08-28 CVE-2013-3495 Permissions, Privileges, and Access Controls vulnerability in multiple products
The Intel VT-d Interrupt Remapping engine in Xen 3.3.x through 4.3.x allows local guests to cause a denial of service (kernel panic) via a malformed Message Signaled Interrupt (MSI) from a PCI device that is bus mastering capable that triggers a System Error Reporting (SERR) Non-Maskable Interrupt (NMI).
4.7
2013-08-28 CVE-2013-2212 Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in XEN
The vmx_set_uc_mode function in Xen 3.3 through 4.3, when disabling caches, allows local HVM guests with access to memory mapped I/O regions to cause a denial of service (CPU consumption and possibly hypervisor or guest kernel panic) via a crafted GFN range.
5.7
2013-08-28 CVE-2013-2211 Permissions, Privileges, and Access Controls vulnerability in XEN
The libxenlight (libxl) toolstack library in Xen 4.0.x, 4.1.x, and 4.2.x uses weak permissions for xenstore keys for paravirtualised and emulated serial console devices, which allows local guest administrators to modify the xenstore value via unspecified vectors.
