After looking at the iDefense advisory, and through the Freetype changelog,
it looks like this is the changeset we need to fix this:
2008-06-08 Werner Lemberg
* src/type1/t1parse.h (T1_ParserRec): Make `base_len' and
`private_len' unsigned.
* src/type1/t1parse.c (read_pfb_tag): Make `asize' unsigned and
* read
it as such.
(T1_New_Parser, T1_Get_Private_Dict): Make `size' unsigned.
* src/base/ftstream.c (FT_Stream_Skip): Reject negative values.
* src/type1/t1load.c (parse_blend_design_positions): Check `n_axis'
for sane value.
Fix typo.
* src/psaux/psobjs.c (ps_table_add): Check `idx' correctly.
* src/truetype/ttinterp (Ins_SHC): Use BOUNDS() to check
`last_point'.
* src/sfnt/ttload.c (tt_face_load_max_profile): Limit
`maxTwilightPoints'.
I'll attach the patch (with comment changes stripped).
