6.4
None Remote Low Not required Partial None Partial
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).
2 CVE-2014-4947 119 Overflow 2014-07-22 2014-07-23
10.0
None Remote Low Not required Complete Complete Complete
Buffer overflow in the HVM graphics console support in Citrix XenServer 6.2 Service Pack 1 and earlier has unspecified impact and attack vectors.
3 CVE-2012-5512 16 DoS +Info 2012-12-13 2013-10-10
3.2
None Local Low Single system Partial None Partial
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.
4 CVE-2012-3516 264 DoS +Priv 2012-11-23 2013-01-31
6.9
None Local Medium Not required Complete Complete Complete
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.
5 CVE-2012-3498 20 DoS 2012-11-23 2013-10-10
5.6
None Local Low Not required Partial None Complete
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.
6 CVE-2012-3496 16 DoS 2012-11-23 2013-10-10
4.7
None Local Medium Not required None None Complete
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.
7 CVE-2012-3495 20 DoS +Priv 2012-11-23 2013-10-10
6.1
None Local Low Not required Partial Partial Complete
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.
8 CVE-2012-3494 264 DoS 2012-11-23 2013-10-10
2.1
None Local Low Not required None None Partial
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.
9 CVE-2012-0217 119 Overflow +Priv 2012-06-12 2013-10-10
7.2
None Local Low Not required Complete Complete Complete
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.
10 CVE-2010-2619 DoS 2010-07-02 2010-07-06
1.9
None Local Medium Not required None None Partial
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."
11 CVE-2010-0633 Bypass 2010-02-12 2010-03-18
4.6
None Local Low Not required Partial Partial Partial
Unspecified vulnerability in Citrix XenServer 5.0 Update 3 and earlier, and 5.5, allows local users to bypass authentication and execute unspecified Xen API (XAPI) calls via unknown vectors.
12 CVE-2008-3253 79 XSS 2008-07-22 2008-09-05
4.3
None Remote Medium Not required None Partial None
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.
