DATE | CVE | VULNERABILITY TITLE | RISK |
---|---|---|---|
2015-03-18 | CVE-2015-2152 | Permissions, Privileges, and Access Controls vulnerability in multiple products Xen 4.5.x and earlier enables certain default backends when emulating a VGA device for an x86 HVM guest qemu even when the configuration disables them, which allows local guest users to obtain access to the VGA console by (1) setting the DISPLAY environment variable, when compiled with SDL support, or connecting to the VNC server on (2) ::1 or (3) 127.0.0.1, when not compiled with SDL support. | 1.9 |
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 |
2015-01-07 | 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-2014-8866 | 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 |
2014-11-24 | CVE-2014-9030 | Improper Input Validation vulnerability in multiple products The do_mmu_update function in arch/x86/mm.c in Xen 3.2.x through 4.4.x does not properly manage page references, which allows remote domains to cause a denial of service by leveraging control over an HVM guest and a crafted MMU_MACHPHYS_UPDATE. | 7.1 |
