1 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.
2 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."
3 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.
4 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.
5 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.
6 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.
7 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.
8 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.
