The paging_invlpg function in include/asm-x86/paging.h in Xen 3.3.x through 4.6.x, when using shadow mode paging or nested virtualization is enabled, allows local HVM guest users to cause a denial of service (host crash) via a non-canonical guest address in an INVVPID instruction, which triggers a hypervisor bug check.
CVE-2018-14007 1 Citrix 1 Xenserver 2018-10-23 10.0 HIGH 9.8 CRITICAL
Citrix XenServer 7.1 and newer allows Directory Traversal.
CVE-2016-9637 1 Citrix 1 Xenserver 2018-02-07 3.7 LOW 7.5 HIGH
The (1) ioport_read and (2) ioport_write functions in Xen, when qemu is used as a device model within Xen, might allow local x86 HVM guest OS administrators to gain qemu process privileges via vectors involving an out-of-range ioport access.
CVE-2016-10024 2 Citrix, Xen 2 Xenserver, Xen 2017-11-03 4.9 MEDIUM 6.0 MEDIUM
Xen through 4.8.x allows local x86 PV guest OS kernel administrators to cause a denial of service (host hang or crash) by modifying the instruction stream asynchronously while performing certain kernel operations.
CVE-2014-4948 1 Citrix 1 Xenserver 2017-08-28 6.4 MEDIUM N/A
Unspecified vulnerability in Citrix XenServer 6.2 Service Pack 1 and earlier allows attackers to cause a denial of service and obtain sensitive information by modifying the guest virtual hard disk (VHD).
CVE-2014-4947 1 Citrix 1 Xenserver 2017-08-28 10.0 HIGH N/A
Buffer overflow in the HVM graphics console support in Citrix XenServer 6.2 Service Pack 1 and earlier has unspecified impact and attack vectors.
CVE-2012-5512 1 Citrix 1 Xenserver 2017-08-28 3.2 LOW N/A
Array index error in the HVMOP_set_mem_access handler in Xen 4.1 allows local HVM guest OS administrators to cause a denial of service (crash) or obtain sensitive information via unspecified vectors.
CVE-2012-3498 2 Citrix, Xen 2 Xenserver, Xen 2017-08-28 5.6 MEDIUM N/A
PHYSDEVOP_map_pirq in Xen 4.1 and 4.2 and Citrix XenServer 6.0.2 and earlier allows local HVM guest OS kernels to cause a denial of service (host crash) and possibly read hypervisor or guest memory via vectors related to a missing range check of map->index.
CVE-2012-3494 2 Citrix, Xen 2 Xenserver, Xen 2017-08-28 2.1 LOW N/A
The set_debugreg hypercall in include/asm-x86/debugreg.h in Xen 4.0, 4.1, and 4.2, and Citrix XenServer 6.0.2 and earlier, when running on x86-64 systems, allows local OS guest users to cause a denial of service (host crash) by writing to the reserved bits of the DR7 debug control register.
CVE-2012-3496 2 Citrix, Xen 2 Xenserver, Xen 2017-08-28 4.7 MEDIUM N/A
XENMEM_populate_physmap in Xen 4.0, 4.1, and 4.2, and Citrix XenServer 6.0.2 and earlier, when translating paging mode is not used, allows local PV OS guest kernels to cause a denial of service (BUG triggered and host crash) via invalid flags such as MEMF_populate_on_demand.
CVE-2008-3253 1 Citrix 1 Xenserver 2017-08-07 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in the XenAPI HTTP interfaces in Citrix XenServer Express, Standard, and Enterprise Edition 4.1.0; Citrix XenServer Dell Edition (Express and Enterprise) 4.1.0; and HP integrated Citrix XenServer (Select and Enterprise) 4.1.0 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
CVE-2016-9383 2 Citrix, Xen 2 Xenserver, Xen 2017-06-30 7.2 HIGH 8.8 HIGH
Xen, when running on a 64-bit hypervisor, allows local x86 guest OS users to modify arbitrary memory and consequently obtain sensitive information, cause a denial of service (host crash), or execute arbitrary code on the host by leveraging broken emulation of bit test instructions.
