CVE-2014-5148 | 1 Xen | 1 Xen | 2017-08-28 | 4.6 MEDIUM | N/A |
Xen 4.4.x, when running on an ARM system and "handling an unknown system register access from 64-bit userspace," returns to an instruction of the trap handler for kernel space faults instead of an instruction that is associated with faults in 64-bit userspace, which allows local guest users to cause a denial of service (crash) and possibly gain privileges via a crafted process. | |||||
CVE-2013-1920 | 1 Xen | 1 Xen | 2017-08-28 | 4.4 MEDIUM | N/A |
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. | |||||
CVE-2013-4368 | 1 Xen | 1 Xen | 2017-08-28 | 1.9 LOW | N/A |
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. | |||||

The pciback_enable_msi function in the PCI backend driver (drivers/xen/pciback/conf_space_capability_msi.c) in Xen for the Linux kernel 2.6.18 and 3.8 allows guest OS users with PCI device access to cause a denial of service via a large number of kernel log messages. NOTE: some of these details are obtained from third party information. | |||||

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. | |||||
CVE-2013-4551 | 1 Xen | 1 Xen | 2017-08-28 | 5.7 MEDIUM | N/A |
Xen 4.2.x and 4.3.x, when nested virtualization is disabled, does not properly check the emulation paths for (1) VMLAUNCH and (2) VMRESUME, which allows local HVM guest users to cause a denial of service (host crash) via unspecified vectors related to "guest VMX instruction execution." | |||||
CVE-2012-5510 | 1 Xen | 1 Xen | 2017-08-28 | 4.7 MEDIUM | N/A |
Xen 4.x, when downgrading the grant table version, does not properly remove the status page from the tracking list when freeing the page, which allows local guest OS administrators to cause a denial of service (hypervisor crash) via unspecified vectors. | |||||
CVE-2013-0154 | 1 Xen | 1 Xen | 2017-08-28 | 1.9 LOW | N/A |
The get_page_type function in xen/arch/x86/mm.c in Xen 4.2, when debugging is enabled, allows local PV or HVM guest administrators to cause a denial of service (assertion failure and hypervisor crash) via unspecified vectors related to a hypercall. | |||||
CVE-2013-0153 | 1 Xen | 1 Xen | 2017-08-28 | 4.7 MEDIUM | N/A |
The AMD IOMMU support in Xen 4.2.x, 4.1.x, 3.3, and other versions, when using AMD-Vi for PCI passthrough, uses the same interrupt remapping table for the host and all guests, which allows guests to cause a denial of service by injecting an interrupt into other guests. | |||||
CVE-2012-6333 | 1 Xen | 1 Xen | 2017-08-28 | 4.7 MEDIUM | N/A |
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. | |||||
