Unsanitised driver domain input in libxl device handling

ISSUE DESCRIPTION libxl's device-handling code freely uses and trusts information from the backend directories in xenstore. The backend domain driver domain can store bogus data in the backend, causing libxl's enquiry functions to fail, confusing management tools. A driver domain can also remove...

Unsanitised guest input in libxl device handling code

ISSUE DESCRIPTION Various parts of libxl device-handling code inappropriately use information from partially guest controlled areas of xenstore principally the frontend directory /local/domain/GUEST/device/TYPE/DEVID, henceforth referred to as FE. The problems vary by device type: For almost all...
