CVE-2016-5302citrixxenserver
EPSS score2.55%
Citrix XenServer 7.0 before Hotfix XS70E003, when a deployment has been upgraded from an earlier release, might allow remote attackers on the management network to "compromise" a host by leveraging credentials for an Active Directory account.CVE-2016-10025alpinexen+4EPSS score0.45%
VMFUNC emulation in Xen 4.6.x through 4.8.x on x86 systems using AMD virtualization extensions (aka SVM) allows local HVM guest OS users to cause a denial of service (hypervisor crash) by leveraging a missing NULL pointer check.CVE-2016-10024alpinexen+4EPSS score0.43%
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-2016-6258alpinexen+4EPSS score0.40%
The PV pagetable code in arch/x86/mm.c in Xen 4.7.x and earlier allows local 32-bit PV guest OS administrators to gain host OS privileges by leveraging fast-paths for updating pagetable entries.CVE-2016-6259alpinexen+4EPSS score0.64%
Xen 4.5.x through 4.7.x do not implement Supervisor Mode Access Prevention (SMAP) whitelisting in 32-bit exception and event delivery, which allows local 32-bit PV guest OS kernels to cause a denial of service (hypervisor and VM crash) by triggering a safety check.CVE-2016-3710canonicalubuntu_linux+36EPSS score0.92%
The VGA module in QEMU improperly performs bounds checking on banked access to video memory, which allows local guest OS administrators to execute arbitrary code on the host by changing access modes after setting the bank register, aka the "Dark Portal" issue.CVE-2016-3712canonicalubuntu_linux+18EPSS score0.51%
Integer overflow in the VGA module in QEMU allows local guest OS users to cause a denial of service (out-of-bounds read and QEMU process crash) by editing VGA registers in VBE mode.CVE-2014-4947citrixxenserverEPSS score5.39%
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-2014-4948citrixxenserverEPSS score1.89%
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-2014-3798citrixxenserverEPSS score1.93%
The Windows Guest Tools in Citrix XenServer 6.2 SP1 and earlier allows remote attackers to cause a denial of service (guest OS crash) via a crafted Ethernet frame.CVE-2008-3253citrixxenserverEPSS score1.97%
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-2012-0217citrixxenserver+9EPSS score39.84%
The x86-64 kernel system-call functionality in Xen 4.1.2 and earlier, as used in Citrix XenServer 6.0.2 and earlier and other products; Oracle Solaris 11 and earlier; illumos before r13724; Joyent SmartOS before 20120614T184600Z; FreeBSD before 9.0-RELEASE-p3; NetBSD 6.0 Beta and earlier; Microsoft Windows Server 2008 R2 and R2 SP1 and Windows 7 Gold and SP1; and possibly other operating systems, when running on an Intel processor, incorrectly uses the sysret path in cases where a certain address is not a canonical address, which allows local users to gain privileges via a crafted application. NOTE: because this issue is due to incorrect use of the Intel specification, it should have been split into separate identifiers; however, there was some value in preserving the original mapping of the multi-codebase coordinated-disclosure effort to a single identifier.CVE-2012-4606citrixxenserverEPSS score0.36%
Citrix XenServer 4.1, 6.0, 5.6 SP2, 5.6 Feature Pack 1, 5.6 Common Criteria, 5.6, 5.5, 5.0, and 5.0 Update 3 contains a Local Privilege Escalation Vulnerability which could allow local users with access to a guest operating system to gain elevated privileges.CVE-2012-5512citrixxenserver+1EPSS score0.41%
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-2012-3495citrixxenserver+2EPSS score0.44%
The physdev_get_free_pirq hypercall in arch/x86/physdev.c in Xen 4.1.x and Citrix XenServer 6.0.2 and earlier uses the return value of the get_free_pirq function as an array index without checking that the return value indicates an error, which allows guest OS users to cause a denial of service (invalid memory write and host crash) and possibly gain privileges via unspecified vectors.CVE-2012-3494citrixxenserver+2EPSS score0.44%
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-2012-3516citrixxenserver+1EPSS score0.36%
The GNTTABOP_swap_grant_ref sub-operation in the grant table hypercall in Xen 4.2 and Citrix XenServer 6.0.2 allows local guest kernels or administrators to cause a denial of service (host crash) and possibly gain privileges via a crafted grant reference that triggers a write to an arbitrary hypervisor memory location.CVE-2012-3498citrixxenserver+2EPSS score0.44%
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-2012-3496citrixxenserver+2EPSS score0.42%
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-2010-2619citrixxenserverEPSS score0.30%
Citrix XenServer 5.0 Update 2 and earlier, and 5.5 Update 1 and earlier, when using a pvops kernel, allows guest users to cause a denial of service in the host via unspecified vectors that trigger "incorrectly set flags."
