Werner Lemberg 5cb356405e Add some variable initializations.
Reported by Richard COOK <rscook@unicode.org>.

earlier.

suzuki toshiya 714ee56ab1 [mac] Unify DARWIN_NO_CARBON with FT_MACINTOSH.
Originally FT_MACINTOSH was a pure auto macro and DARWIN_NO_CARBON
was a configurable macro to disable Carbon-dependent code.  Because
now configure script sets DARWIN_NO_CARBON by default and disables
Darwin & Carbon-dependent codes, these macros can be unified.
FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON
(defined by default) is removed, because DARWIN_NO_CARBON violates
FT_XXX naming convention of public macros, and a macro configured by
default is not portable for the building without configure (e.g.
make devel).

* builds/unix/configure.raw: Define FT_MACINTOSH if Carbon-based
old Mac font support is requested and Carbon is available.
* builds/unix/ftconfig.in: Undefine FT_MACINTOSH when the support
for Mac OS X without Carbon (e.g.  Mac OS X 10.4 for ppc64) is
requested.
* include/freetype/config/ftconfig.in: Ditto.
* builds/vms/ftconfig.h: Ditto.

* src/base/ftbase.h: Remove DARWIN_NO_CARBON.
* src/base/ftbase.c: Ditto.
* src/base/ftobjs.c: Ditto.
* src/base/ftrfork.c: Ditto.

* src/base/ftmac.c: Compile the body if FT_MACINTOSH is defined
(same with TT_USE_BYTECODE_INTERPRETER in ttinterp.c).
* builds/mac/ftmac.c: Ditto.

* builds/mac/FreeType.m68k_cfm.make.txt: Define FT_MACINTOSH.
* builds/mac/FreeType.m68k_far.make.txt: Ditto.
* builds/mac/FreeType.ppc_classic.make.txt: Ditto.

suzuki toshiya 2968bd6098 Fix Savannah bug #34728 (`make devel' on Mac OS X).

suzuki toshiya eba2781ab9 [apinames] Fix the overflow of signed integer hash.
* src/tools/apinames.c (names_add): Change the type of `h' from
int to unsigned int, to prevent undefined behaviour in the
overflow of signed integers (overflow of unsigned int is defined
to be wrap around).  Found by clang test suggested by Sean
McBride.

Werner Lemberg ed54e43aed [bdf] Fix Savannah bug #34896.
ENCODING now covers the whole Unicode range.

Note, however, that this change is quite expensive since it
increases the size of three arrays by almost 400kByte in total.  The
right fix is to replace the logic with something smarter.
Additionally, there exist very old BDFs for three-byte CCCII
encoding which exceeds the range of Unicode (another reason to have
a smarter logic).

* src/bdf/bdf.h (bdf_font_t): Increase size of `nmod' and `umod'
arrays.
* src/bdf/bdflib.c (bdf_parse_t): Increase size of `have' array.

Tomas Hoger 487913d9a6 Slightly improve LZW_CLEAR handling.
* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>:
Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are
handled as clear codes.  This also re-sets old_code and old_char to
predictable values, which is a little better than using `random'
ones if the code following LZW_CLEAR is invalid.
2011-09-11 09:18:10 +02:00
Tomas Hoger 83cb6c0049 Add explicit LZW decompression stack size limit.
Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is
constructed correctly.  It's even less than that, see e.g.
libarchive code comment for a better size upper bound:

  http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121

This patch adds explicit stack size limit, enforced when stack is
realloced.

An alternative is to ensure that code < state->prefix[code - 256]
when traversing prefix table.  Such check is less efficient and
should not be required if prefix table is constructed correctly in
the first place.

* src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it.
2011-09-11 09:13:45 +02:00
Tomas Hoger 86c3c69c15 Protect against loops in the prefix table.
LZW decompressor did not sufficiently check codes read from the
input LZW stream.  A specially-crafted or corrupted input could
create a loop in the prefix table, which leads to memory usage
spikes, as there's no decompression stack size limit.

* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_START>: First
code in valid LZW stream must be 0..255.
<FT_LZW_PHASE_CODE>: In the special KwKwK case, code == free_ent,
code > free_ent is invalid.
