integer overflow in XvQueryPortAttributes() [CVE-2013-1989 1/3]

The num_attributes & text_size members of the reply are both CARD32s
and need to be bounds checked before multiplying & adding them together
to come up with the total size to allocate, to avoid integer overflow
leading to underallocation and writing data from the network past the
end of the allocated buffer.
