1 CVE-2014-1950 399 DoS +Priv 2014-02-14 2014-04-19
4.6
None Local Low Not required Partial Partial Partial
Use-after-free vulnerability in the xc_cpupool_getinfo function in Xen 4.1.x through 4.3.x, when using a multithreaded toolstack, does not properly handle a failure by the xc_cpumap_alloc function, which allows local users with access to management functions to cause a denial of service (heap corruption) and possibly gain privileges via unspecified vectors.
2 CVE-2014-1896 20 DoS +Priv 2014-04-01 2014-04-19
4.9
None Local Network Medium Single system Partial Partial Partial
The (1) do_send and (2) do_recv functions in io.c in libvchan in Xen 4.2.x, 4.3.x, and 4.4-RC series allows local guests to cause a denial of service or possibly gain privileges via crafted xenstore ring indexes, which triggers a "read or write past the end of the ring."
3 CVE-2014-1666 264 DoS +Priv 2014-01-26 2014-04-19
8.3
None Local Network Low Not required Complete Complete Complete
The do_physdev_op function in Xen 4.1.5, 4.1.6.1, 4.2.2 through 4.2.3, and 4.3.x does not properly restrict access to the (1) PHYSDEVOP_prepare_msix and (2) PHYSDEVOP_release_msix operations, which allows local PV guests to cause a denial of service (host or guest malfunction) or possibly gain privileges via unspecified vectors.
4 CVE-2013-6400 264 DoS +Priv 2013-12-13 2014-04-19
6.8
None Local Network High Not required Complete Complete Complete
Xen 4.2.x and 4.3.x, when using Intel VT-d and a PCI device has been assigned, does not clear the flag that suppresses IOMMU TLB flushes when unspecified errors occur, which causes the TLB entries to not be flushed and allows local guest administrators to cause a denial of service (host crash) or gain privileges via unspecified vectors.
5 CVE-2013-6375 264 DoS +Priv 2013-11-23 2014-01-03
7.9
None Local Network Medium Not required Complete Complete Complete
Xen 4.2.x and 4.3.x, when using Intel VT-d for PCI passthrough, does not properly flush the TLB after clearing a present translation table entry, which allows local guest administrators to cause a denial of service or gain privileges via unspecified vectors related to an "inverted boolean parameter."
6 CVE-2013-4554 264 +Priv 2013-12-24 2014-04-19
5.2
None Local Network Low Single system Partial Partial Partial
Xen 3.0.3 through 4.1.x (possibly 4.1.6.1), 4.2.x (possibly 4.2.3), and 4.3.x (possibly 4.3.1) does not properly prevent access to hypercalls, which allows local guest users to gain privileges via a crafted application running in ring 1 or 2.
7 CVE-2013-4344 119 Overflow +Priv 2013-10-04 2014-03-05
6.0
None Local High Single system Complete Complete Complete
Buffer overflow in the SCSI implementation in QEMU, as used in Xen, when a SCSI controller has more than 256 attached devices, allows local users to gain privileges via a small transfer buffer in a REPORT LUNS command.
8 CVE-2013-4329 264 DoS +Priv 2013-09-12 2014-04-19
6.5
None Local Network High Single system Complete Complete Complete
The xenlight library (libxl) in Xen 4.0.x through 4.2.x, when IOMMU is disabled, provides access to a busmastering-capable PCI passthrough device before the IOMMU setup is complete, which allows local HVM guest domains to gain privileges or cause a denial of service via a DMA instruction.
9 CVE-2013-2072 119 DoS Overflow +Priv Mem. Corr. 2013-08-28 2014-04-19
7.4
None Local Network Medium Single system Complete Complete Complete
Buffer overflow in the Python bindings for the xc_vcpu_setaffinity call in Xen 4.0.x, 4.1.x, and 4.2.x allows local administrators with permissions to configure VCPU affinity to cause a denial of service (memory corruption and xend toolstack crash) and possibly gain privileges via a crafted cpumap.
10 CVE-2013-1920 264 +Priv 2013-04-12 2014-04-19
4.4
None Local Medium Not required Partial Partial Partial
Xen 4.2.x, 4.1.x, and earlier, when the hypervisor is running "under memory pressure" and the Xen Security Module (XSM) is enabled, uses the wrong ordering of operations when extending the per-domain event channel tracking table, which causes a use-after-free and allows local guest kernels to inject arbitrary events and gain privileges via unspecified vectors.
11 CVE-2013-1432 399 DoS +Priv 2013-08-28 2014-04-19
7.4
None Local Network Medium Single system Complete Complete Complete
Xen 4.1.x and 4.2.x, when the XSA-45 patch is in place, does not properly maintain references on pages stored for deferred cleanup, which allows local PV guest kernels to cause a denial of service (premature page free and hypervisor crash) or possible gain privileges via unspecified vectors.
12 CVE-2012-5513 20 DoS +Priv 2012-12-13 2014-04-19
6.9
None Local Medium Not required Complete Complete Complete
The XENMEM_exchange handler in Xen 4.2 and earlier does not properly check the memory address, which allows local PV guest OS administrators to cause a denial of service (crash) or possibly gain privileges via unspecified vectors that overwrite memory in the hypervisor reserved range.
13 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.
14 CVE-2012-3515 20 +Priv 2012-11-23 2014-03-05
7.2
None Local Low Not required Complete Complete Complete
Qemu, as used in Xen 4.0, 4.1 and possibly other products, when emulating certain devices with a virtual console backend, allows local OS guest users to gain privileges via a crafted escape VT100 sequence that triggers the overwrite of a "device model's address space."
15 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.
16 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.
17 CVE-2011-1763 DoS +Priv 2014-01-07 2014-01-08
7.7
None Local Network Low Single system Complete Complete Complete
