Alan Coopersmith 5fbd8c45b4 Xdmx: integer overflow in GetGLXFBConfigs() ...

numFBConfigs & numAttribs are CARD32s and need to be bounds checked before
multiplying by structure sizes 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.
