Ben Wagner 3829fdaae5 Avoid overflow in COLR bounds checks. 
The values read into `base_glyphs_offset_v1` and `layer_offset_v1` may
be in the range 0xFFFFFFFD-0xFFFFFFFF. On systems where `unsigned long`
is 32 bits adding 4 to such values will wrap and pass bounds checks but
accessing values at such offsets will be out of bounds.

On the other hand `table_size` has already been tested to be at least
`COLRV1_HEADER_SIZE` (34) so it is safe to subtract 4 from it.

* src/sfnt/ttcolr.c (tt_face_load_colr): subtract 4 from `table_size`
instead of adding 4 to font data offsets in bounds checks

Fixes: https://crbug.com/1469348

Alexei Podtelezhnikov 95a872085e * src/base/ftobjs.c (open_face_from_buffer): Silence `maybe-uninitialized`. 
We never call this function without a `driver_name` (#1245).

Alexei Podtelezhnikov b2584c738f [truetype] Reduce v40 footprint.

which was undefined for a while now.

* include/freetype/internal/tttypes.h: Ditto.
* src/truetype/truetype.c: Ditto.
* src/truetype/ttdriver.c: Ditto.

Jouk Jansen 9e3c5d7e18 * vms_make.com: Provide separate library compiled with C++. 
Some types on OpenVMS x86_64 (for example, `long') have different sizes
depending on whether compiled with either C or C++.  In particular,
X-Windows applications crash if linked with the C++ version.

This patch makes `vms_make.com` create a second version of the FreeType
library compiled with C++ if OpenVMS is running on the x86_64 platform.

Jouk Jansen f7ae7e88e9 * vms_make.com: Fix typos. 2023-07-21 21:33:20 +02:00
Jouk Jansen 7c542d02bf * src/smooth/ftgrays.c (FT_SSE2): Fix definition for VMS. 2023-07-21 21:31:28 +02:00
Jouk Jansen 5769f13a6b vms_make.com: Make use of additional libraries optional. 
Check whether `.olb` files are present.

Also check for the HarfBuzz library.
 2023-07-19 13:41:04 +02:00
Jouk Jansen e8aa5af936 vms_make.com: Add `/warn=noinfo` to `CFLAGS`. 
This reduces enormously the informationals while compiling on x86_64 (i.e.,
which `.h` file is inluded form where).

This is a fix for commit 85167dbd5, reported as

  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=60615

(woff2_open_font): Use it to limit the maximum size of an uncompressed WOFF2
font.
 2023-07-16 07:40:32 +02:00
Werner Lemberg 3c92e7bfc2 [cff] Fix compiler warning.

function.
 2023-07-14 18:58:55 +02:00
Ben Wagner 85167dbd50 [woff2] Remove sfnt size guess check 
In WOFF the `totalSfntSize` must be correct, however in WOFF2 this value
is now just a hint and a conforming implementation must not reject
otherwise valid data if the `totalSfntSize` turns out not to be exact.

* src/sfnt/sfwoff2.c (woff2_open_font): remove check that uncompressed
woff2 data would fit in the sfnt size guess.

Fixes: #1235
