Information leak through fbld instruction emulation

ISSUE DESCRIPTION The emulation of the fbld instruction which is used during I/O emulation uses the wrong variable for the source effective address. As a result, the actual address used is an uninitialised bit pattern from the stack. A malicious guest might be able to find out information about t...

libxl partially sets up HVM passthrough even with disabled iommu

ISSUE DESCRIPTION With HVM domains, libxl's setup of PCI passthrough devices does the IOMMU setup after giving via the device model the guest access to the hardware and advertising it to the guest. If the IOMMU is disabled the overall setup fails, but after the device has been made available to t...
