2006-05-02  David Turner  <[e-mail]>

	Update the memory management functions and macros to safely deal
	with array size buffer overflows.  This corresponds to attemps to
	allocate arrays that are too large.  For an example, consider the
	following code:

	  count = read_uint32_from_file(); array = malloc( sizeof ( Item ) *
	  count ); for ( nn = 0; nn < count; nn++ )
	    array[nn] = read_item_from_file();

	If `count' is larger than `FT_UINT_MAX/sizeof(Item)', the
	multiplication overflows, and the array allocated os smaller than
	the data read from the file.  In this case, the heap will be
	trashed, and this can be used as a denial-of-service attack, or make
	the engine crash later.

	The FT_ARRAY_NEW and FT_ARRAY_RENEW macros now ensure that the new
	count is no larger than `FT_INT_MAX/item_size', otherwise a new
	error code `FT_Err_Array_Too_Large' will be returned.

	Note that the memory debugger now works again when FT_DEBUG_MEMORY
	is defined.  FT_STRICT_ALIASING has disappeared; the corresponding
	code is now the default.


	* include/freetype/config/ftconfig.h (FT_BASE_DEF) [!__cplusplus]:
	Don't use `extern'.

	* include/freetype/fterrdef.h (FT_Err_Array_Too_Large): New error
	code.

	* include/freetype/internal/ftmemory.h (FT_DEBUG_INNER)
	[FT_DEBUG_MEMORY]: New macro.
	(ft_mem_realloc, ft_mem_qrealloc): Pass new object size count also.

	FT_MEM_FREE): Redefine.
	(FT_MEM_NEW_ARRAY, FT_MEM_RENEW_ARRAY, FT_MEM_QNEW_ARRAY,
	FT_MEM_QRENEW_ARRAY): Redefine.
	(FT_ALLOC_MULT, FT_REALLOC_MULT, FT_MEM_QALLOC_MULT,
	FT_MEM_QREALLOC_MULT): New macros.  Update callers where
	appropriate.
	(FT_MEM_SET_ERROR): Slightly redefine.

	[FT_DEBUG_MEMORY]: New global variables, replacing...
	(FT_MemTable_Rec) [FT_DEBUG_MEMORY]: Remove `filename' and
	`line_no'.  Update all callers.
	(ft_mem_debug_alloc) [FT_DEBUG_MEMORY]: Avoid possible integer
	overflow.
	(ft_mem_alloc_debug, ft_mem_realloc_debug, ft_mem_qalloc_debug,
	ft_mem_qrealloc_debug, ft_mem_free_debug): Removed.

	* src/base/ftmac.c (read_lwfn): Catch integer overflow.
	* src/base/ftrfork.c (raccess_guess_darwin_hfsplus): Ditto.
	* src/base/ftutil.c: Remove special code for FT_STRICT_ALIASING.
	(ft_mem_alloc. ft_mem_realloc, ft_mem_qrealloc): Rewrite.


	* include/freetype/ftstream.h (FT_FRAME_ENTER, FT_FRAME_EXIT,
	FT_FRAME_EXTRACT, FT_FRAME_RELEASE): Use FT_DEBUG_INNER to report the
	place where the frames were entered, extracted, exited or released
	in the memory debugger.

	* src/base/ftstream.c (FT_Stream_ReleaseFrame) [FT_DEBUG_MEMORY]:
	Call ft_mem_free.
	(FT_Stream_EnterFrame) [FT_DEBUG_MEMORY]: Use ft_mem_qalloc.

	* src/base/ftobjs.c (Mac_Read_POST_Resource): Correct pfb_pos
