CVE-2015-2152
Xen 4.5.x and earlier enables certain default backends when emulating a VGA device for an x86 HVM guest qemu even when the configuration disables them, which allows local guest users to obtain access to the VGA console by 1 setting the DISPLAY environment variable, when compiled with SDL support,...
xen-tools -- HVM qemu unexpectedly enabling emulated VGA graphics backends
The Xen Project reports: When instantiating an emulated VGA device for an x86 HVM guest qemu will by default enable a backend to expose that device, either SDL or VNC depending on the version of qemu and the build time configuration. The libxl toolstack library does not explicitly disable these...

Information leak via internal x86 system device emulation
ISSUE DESCRIPTION Emulation routines in the hypervisor dealing with certain system devices check whether the access size by the guest is a supported one. When the access size is unsupported these routines failed to set the data to be returned to the guest for read accesses, so that hypervisor sta...
