Bug #30468: column level privileges not respected when joining tables

Browse Source 
When expanding a * in a USING/NATURAL join the check for table access
for both tables in the join was done using the grant information of the
first one.
Fixed by getting the grant information for the current table while 
iterating through the columns of the join.
