* include/freetype/ftstream.h, src/base/ftstream.c: modifying
various frame-related functions to report the place where the
frames were entered/extracted/exited/released in the memory debugger.
* 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.
* include/freetype/internal/ftmemory.h, src/base/ftbitmap.c,
src/base/ftmac.c, src/base/ftrfork.c, src/lzw/ftzopen.c,
src/raster/ftrend1.c, src/sfnt/ttpost.c, src/truetype/ttgxvar.c,
src/type42/t42parse.c, src/winfonts/winfnt.c: hardening the code
against out-of-bounds conditions when allocating arrays. This is
for the cases where FT_NEW_ARRAY and FT_RENEW_ARRAY are not used
already. Introducing the new FT_ALLOC_MULT and FT_REALLOC_MULT
macros.
* src/base/ftstream.c (FT_Stream_ReleaseFrame) [FT_DEBUG_MEMORY]:
Call ft_mem_free.
(FT_Stream_EnterFrame) [FT_DEBUG_MEMORY]: Use ft_mem_qalloc.
(FT_Stream_ExitFrame) [FT_DEBUG_MEMORY]: Use ft_mem_free.
* include/freetype/fterrdef.h, include/freetype/config/ftconfig.h,
include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c,
src/base/ftutil.c: udpating 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:
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();
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
will overflow and the array allocated will be 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, or make the engine crash later.
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 macro now check that the new
count is no more than FT_INT_MAX/item_size, otherwise, a new error,
named 'FT_Err_Array_Too_Large' will be returned.
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, and FT_STRICT_ALIASING has disappeared, the corresponding
code being now the default.

code.

to copy to pfb_lenpos.

(FT_MemTable_Rec) [FT_DEBUG_MEMORY]: Remove `filename' and
`line_no'. Update all callers.

overflow.
