CVE-2013-2078
Xen 4.0.2 through 4.0.4, 4.1.x, and 4.2.x allows local PV guest users to cause a denial of service hypervisor crash via certain bit combinations to the XSETBV instruction...
CVE-2013-1919
Xen 4.2.x and 4.1.x does not properly restrict access to IRQs, which allows local stub domain clients to gain access to IRQs and cause a denial of service via vectors related to "passed-through IRQs or PCI devices."...
Format string
qemu-nbd in QEMU, as used in Xen 4.2.x, determines the format of a raw disk image based on the header, which allows local guest OS administrators to read arbitrary files on the host by modifying the header to identify a different format, which is used when the guest is restarted, a different...

Design/Logic Flaw
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 injec...
Design/Logic Flaw
The dohvmop function in xen/arch/x86/hvm/hvm.c in Xen 4.2.x on the x8632 platform does not prevent HVMPARAMNESTEDHVM aka nested virtualization operations, which allows guest OS users to cause a denial of service long-duration page mappings and host OS crash by leveraging administrative access to ...
