CVE-2015-7311 |
libxl in Xen 4.1.x through 4.6.x does not properly handle the readonly flag on disks when using the qemu-xen device model, which allows local guest users to write to a read-only disk image. Published: October 01, 2015; 4:59:06 PM -0400 |
V3.x:(not available) V2.0: 3.6 LOW |
CVE-2015-5166 |
Use-after-free vulnerability in QEMU in Xen 4.5.x and earlier does not completely unplug emulated block devices, which allows local HVM guest users to gain privileges by unplugging a block device twice. Published: August 12, 2015; 10:59:25 AM -0400 |
V3.x:(not available) V2.0: 7.2 HIGH |
CVE-2015-5165 |
The C+ mode offload emulation in the RTL8139 network card device model in QEMU, as used in Xen 4.5.x and earlier, allows remote attackers to read process heap memory via unspecified vectors. Published: August 12, 2015; 10:59:24 AM -0400 |
V3.x:(not available) V2.0: 9.3 HIGH |
CVE-2015-5154 |
Heap-based buffer overflow in the IDE subsystem in QEMU, as used in Xen 4.5.x and earlier, when the container has a CDROM drive enabled, allows local guest users to execute arbitrary code on the host via unspecified ATAPI commands. Published: August 12, 2015; 10:59:23 AM -0400 |
V3.x:(not available) V2.0: 7.2 HIGH |
CVE-2015-3340 |
Xen 4.2.x through 4.5.x does not initialize certain fields, which allows certain remote service domains to obtain sensitive information from memory via a (1) XEN_DOMCTL_gettscinfo or (2) XEN_SYSCTL_getdomaininfolist request. Published: April 28, 2015; 10:59:02 AM -0400 |
V3.x:(not available) V2.0: 2.9 LOW |
CVE-2015-2152 |
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. Published: March 18, 2015; 12:59:02 PM -0400 |

CVE-2015-0361 |
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. Published: January 07, 2015; 2:59:05 PM -0500 |
V3.x:(not available) V2.0: 7.8 HIGH |
CVE-2014-9066 |
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. Published: December 09, 2014; 6:59:09 PM -0500 |
V3.x:(not available) V2.0: 4.7 MEDIUM |
CVE-2014-9065 |
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. Published: December 09, 2014; 6:59:08 PM -0500 |
V3.x:(not available) V2.0: 4.4 MEDIUM |
CVE-2014-7155 |
The x86_emulate function in arch/x86/x86_emulate/x86_emulate.c in Xen 4.4.x and earlier does not properly check supervisor mode permissions, which allows local HVM users to cause a denial of service (guest crash) or gain guest kernel mode privileges via vectors involving an (1) HLT, (2) LGDT, (3) LIDT, or (4) LMSW instruction. Published: October 02, 2014; 10:55:05 AM -0400 |
V3.x:(not available) V2.0: 5.8 MEDIUM |
CVE-2013-4494 |
Xen before 4.1.x, 4.2.x, and 4.3.x does not take the page_alloc_lock and grant_table.lock in the same order, which allows local guest administrators with access to multiple vcpus to cause a denial of service (host deadlock) via unspecified vectors. Published: November 02, 2013; 2:55:03 PM -0400 |
V3.x:(not available) V2.0: 5.2 MEDIUM |
