13 May 2013 — Xen 3.1 through 4.x, when running 64-bit hosts on Intel CPUs, does not clear the NT flag when using an IRET after a SYSENTER instruction, which allows PV guest users to cause a denial of service (hypervisor crash) by triggering a #GP fault, which is not properly handled by another IRET instruction. Xen 3.1 a la 4.x, cuando ejecuta hosts con arquitectura de 64 bits en CPUs Intel, no limpia la bandera NT cuan emplea una IRET después de una instrucción SYSENTER, lo que permite a usuarios PV provocar una denega... • http://lists.fedoraproject.org/pipermail/package-announce/2013-May/104537.html • CWE-20: Improper Input Validation •

13 May 2013 — Xen 4.x, when using Intel VT-d for a bus mastering capable PCI device, does not properly check the source when accessing a bridge device's interrupt remapping table entries for MSI interrupts, which allows local guest domains to cause a denial of service (interrupt injection) via unspecified vectors.

12 Apr 2013 — 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.
