b2ea64bcc6 Additional fix for Savannah bug #30306. 
* src/base/ftobjs.c (Mac_Read_POST_Resource): If the type
of the POST fragment is 0, the segment is completely ignored.
The declared length of the segment is not cared at all.
According to Adobe Technical Note 5040, type 0 segment is
comment only and should not be loaded for the interpreter.
Reported by Robert Swiecki.

5ef20c8c1d Initial fix for Savannah bug #30306. 
* src/base/ftobjs.c (Mac_Read_POST_Resource): Check `rlen'
the length of fragment declared in the POST fragment header
and prevent an underflow in length calculation. Some fonts
set the length to zero in spite of the exist of following
16bit `type'. Reported by Robert Swiecki.

size during gathering PFB fragments embedded in LaserWriter PS
font for Macintosh. Reported by Robert Swiecki.

6305b869d8 Fix Savannah bug #30263. 
* src/smooth/ftgrays.c (gray_render_span): Use cast to `unsigned
int' to avoid integer overflow.

* src/smooth/ftsmooth.c (ft_smooth_render_generic): Use smaller

related to the bug fix but makes sense anyway.
 2010-06-30 18:24:33 +02:00

The previous version was too aggressive, as demonstrated in
http://lists.gnu.org/archive/html/freetype-devel/2010-06/msg00020.html.

(BDF_Err_Missing_Fontboundingbox_Field): New error code.

* src/bdf/bdflib.c (_bdf_parse_start): Check for missing
`FONTBOUNDINGBOX' field.
Avoid memory leak if there are multiple `FONT' lines (which is

8d22746c9e Fix Savannah bug #30106. 
Point numbers for FreeType's implementation of hinting masks are
collected before the final number of points of a glyph has been
determined; in particular, the code for handling the `endchar'
opcode can reduce the number of points.

* src/pshinter/pshalgo.c (psh_glyph_find_strong_points): Assure that
`end_point' is not larger than `glyph->num_points'.

with two straight lines.  See this thread for more:
