2006-05-02  David Turner  <>

	Update the memory management functions and macros to safely deal
	with array size buffer overflows.  This corresponds to attempts 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

	FT_MEM_QREALLOC_MULT): New macros.  Update callers where
	(FT_MEM_SET_ERROR): Slightly redefine.

	* src/base/ftdbgmem.c (_ft_debug_file, _ft_debug_lineno)
	[FT_DEBUG_MEMORY]: New global variables, replacing...
	(FT_MemTable_Rec) [FT_DEBUG_MEMORY]: Remove `filename' and

2006-04-30  suzuki toshiya  <>

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

	* src/truetype/ttgload.c (TT_Load_Glyph): Only translate outline

	rendering of buggy fonts.

	TT_Vary_Get_Glyph_Deltas now.
	(TT_LOADER_SET_PP): New macro to calculate and set the four phantom

	Scale all four phantom points.
	Split off some functionality to ...
	(TT_Process_Composite_Component, TT_Process_Composite_Glyph): These
	new functions.
	(TT_Load_Glyph): Set various fields of `glyph' here, not in
	load_truetype_glyph and compute_glyph_metrics.

	  . loader->pp3.y and loader->pp4.y are in 26.6 format, not in font

	    there is no need to adjust `top'.
