Multiple integer overflows in the (1) FLASK_GETBOOL, (2) FLASK_SETBOOL, (3) FLASK_USER, and (4) FLASK_CONTEXT_TO_SID suboperations in the flask hypercall in Xen 4.3.x, 4.2.x, 4.1.x, 3.2.x, and earlier, when XSM is enabled, allow local users to cause a denial of service (processor fault) via unspecified vectors, a different vulnerability than CVE-2014-1892, CVE-2014-1893, and CVE-2014-1894. | |||||
CVE-2014-2599 | 1 Xen | 1 Xen | 2017-01-07 | 4.9 MEDIUM | N/A |
The HVMOP_set_mem_access HVM control operations in Xen 4.1.x for 32-bit and 4.1.x through 4.4.x for 64-bit allow local guest administrators to cause a denial of service (CPU consumption) by leveraging access to certain service domains for HVM guests and a large input. | |||||
CVE-2014-1896 | 1 Xen | 1 Xen | 2017-01-07 | 4.9 MEDIUM | N/A |
The (1) do_send and (2) do_recv functions in io.c in libvchan in Xen 4.2.x, 4.3.x, and 4.4-RC series allows local guests to cause a denial of service or possibly gain privileges via crafted xenstore ring indexes, which triggers a "read or write past the end of the ring." | |||||
CVE-2014-1892 | 1 Xen | 1 Xen | 2017-01-07 | 5.2 MEDIUM | N/A |
Xen 3.3 through 4.1, when XSM is enabled, allows local users to cause a denial of service via vectors related to a "large memory allocation," a different vulnerability than CVE-2014-1891, CVE-2014-1893, and CVE-2014-1894. | |||||
CVE-2013-4370 | 1 Xen | 1 Xen | 2017-01-07 | 4.6 MEDIUM | N/A |
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. | |||||
CVE-2013-4553 | 1 Xen | 1 Xen | 2017-01-07 | 5.2 MEDIUM | N/A |
The XEN_DOMCTL_getmemlist hypercall in Xen 3.4.x through 4.3.x (possibly 4.3.1) does not always obtain the page_alloc_lock and mm_rwlock in the same order, which allows local guest administrators to cause a denial of service (host deadlock). | |||||
CVE-2013-4554 | 1 Xen | 1 Xen | 2017-01-07 | 5.2 MEDIUM | N/A |
Xen 3.0.3 through 4.1.x (possibly 4.1.6.1), 4.2.x (possibly 4.2.3), and 4.3.x (possibly 4.3.1) does not properly prevent access to hypercalls, which allows local guest users to gain privileges via a crafted application running in ring 1 or 2. | |||||
CVE-2013-4329 | 1 Xen | 1 Xen | 2017-01-07 | 6.5 MEDIUM | N/A |
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. | |||||
CVE-2013-4356 | 1 Xen | 1 Xen | 2017-01-07 | 5.4 MEDIUM | N/A |
Xen 4.3.x writes hypervisor mappings to certain shadow pagetables when live migration is performed on hosts with more than 5TB of RAM, which allows local 64-bit PV guests to read or write to invalid memory and cause a denial of service (crash). | |||||

Buffer overflow in the Python bindings for the xc_vcpu_setaffinity call in Xen 4.0.x, 4.1.x, and 4.2.x allows local administrators with permissions to configure VCPU affinity to cause a denial of service (memory corruption and xend toolstack crash) and possibly gain privileges via a crafted cpumap. | |||||
CVE-2013-2212 | 1 Xen | 1 Xen | 2016-12-22 | 5.7 MEDIUM | N/A |
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. | |||||
CVE-2015-8338 | 1 Xen | 1 Xen | 2016-12-07 | 7.2 HIGH | N/A |
Xen 4.6.x and earlier does not properly enforce limits on page order inputs for the (1) XENMEM_increase_reservation, (2) XENMEM_populate_physmap, (3) XENMEM_exchange, and possibly other HYPERVISOR_memory_op suboperations, which allows ARM guest OS administrators to cause a denial of service (CPU consumption, guest reboot, or watchdog timeout and host reboot) and possibly have unspecified other impact via unknown vectors. | |||||
CVE-2015-6654 | 1 Xen | 1 Xen | 2016-12-07 | 2.1 LOW | N/A |
The xenmem_add_to_physmap_one function in arch/arm/mm.c in Xen 4.5.x, 4.4.x, and earlier does not limit the number of printk console messages when reporting a failure to retrieve a reference on a foreign page, which allows remote domains to cause a denial of service by leveraging permissions to map the memory of a foreign guest. | |||||
CVE-2016-3960 | 3 Fedoraproject, Oracle, Xen | 3 Fedora, Vm Server, Xen | 2016-12-03 | 7.2 HIGH | 8.8 HIGH |

CVE-2016-3157 | 2 Canonical, Xen | 2 Ubuntu Linux, Xen | 2016-12-03 | 7.2 HIGH | 7.8 HIGH |
The __switch_to function in arch/x86/kernel/process_64.c in the Linux kernel does not properly context-switch IOPL on 64-bit PV Xen guests, which allows local guest OS users to gain privileges, cause a denial of service (guest OS crash), or obtain sensitive information by leveraging I/O port access. |
