| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2015-03-12 | CVE-2015-2151 | Permissions, Privileges, and Access Controls vulnerability in multiple products The x86 emulator in Xen 3.2.x through 4.5.x does not properly ignore segment overrides for instructions with register operands, which allows local guest users to obtain sensitive information, cause a denial of service (memory corruption), or possibly execute arbitrary code via unspecified vectors. | 7.2 |
| 2015-03-12 | CVE-2015-2045 | Information Exposure vulnerability in multiple products The HYPERVISOR_xen_version hypercall in Xen 3.2.x through 4.5.x does not properly initialize data structures, which allows local guest users to obtain sensitive information via unspecified vectors. | 2.1 |
| 2015-03-12 | CVE-2015-2044 | Information Exposure vulnerability in XEN The emulation routines for unspecified X86 devices in Xen 3.2.x through 4.5.x does not properly initialize data, which allow local HVM guest users to obtain sensitive information via vectors involving an unsupported access size. | 2.1 |
| 2015-02-09 | CVE-2015-1563 | Resource Management Errors vulnerability in multiple products The ARM GIC distributor virtualization in Xen 4.4.x and 4.5.x allows local guests to cause a denial of service by causing a large number messages to be logged. | 2.1 |
| 2015-01-12 | CVE-2014-6268 | Resource Management Errors vulnerability in XEN 4.4.0/4.4.1 The evtchn_fifo_set_pending function in Xen 4.4.x allows local guest users to cause a denial of service (host crash) via vectors involving an uninitialized FIFO-based event channel control block when (1) binding or (2) moving an event to a different VCPU. | 4.9 |
| 2015-01-07 | CVE-2015-0361 | Use After Free Denial of Service vulnerability in Xen Use-after-free vulnerability in Xen 4.2.x, 4.3.x, and 4.4.x allows remote domains to cause a denial of service (system crash) via a crafted hypercall during HVM guest teardown. | 7.8 |
| 2014-12-09 | CVE-2014-9066 | Code vulnerability in multiple products Xen 4.4.x and earlier, when using a large number of VCPUs, does not properly handle read and write locks, which allows local x86 guest users to cause a denial of service (write denial or NMI watchdog timeout and host crash) via a large number of read requests, a different vulnerability than CVE-2014-9065. | 4.7 |
| 2014-12-09 | CVE-2014-9065 | Code vulnerability in multiple products common/spinlock.c in Xen 4.4.x and earlier does not properly handle read and write locks, which allows local x86 guest users to cause a denial of service (write denial or NMI watchdog timeout and host crash) via a large number of read requests, a different vulnerability to CVE-2014-9066. | 4.4 |
| 2014-12-01 | CVE-2014-8867 | Code vulnerability in multiple products The acceleration support for the "REP MOVS" instruction in Xen 4.4.x, 3.2.x, and earlier lacks properly bounds checking for memory mapped I/O (MMIO) emulated in the hypervisor, which allows local HVM guests to cause a denial of service (host crash) via unspecified vectors. | 4.9 |
| 2014-12-01 | CVE-2014-8866 | Code vulnerability in multiple products The compatibility mode hypercall argument translation in Xen 3.3.x through 4.4.x, when running on a 64-bit hypervisor, allows local 32-bit HVM guests to cause a denial of service (host crash) via vectors involving altering the high halves of registers while in 64-bit mode. | 4.7 |
