Description Josh Bressers 2006-05-15 13:58:51 EDT

+++ This bug was initially created as a clone of Bug #190593 +++

Several integer overflow bugs in freetype have been fixed in CVS.  The details
are below.

The descriptions are the CVS commit messages.  That patch for each particular
comment is keyed off it's # identifier.

* Integer overflow

    #2
    * src/bdf/bdflib.c (ERRMSG4): New macro.
      (_bdf_parse_glyphs): Handle invalid BBX values.
    * include/freetype/fterrdef.h (FT_Err_Bbx_Too_Big): New error
      macro.

    #3
    * src/sfnt/ttcmap.c (tt_face_build_cmaps): Handle invalid offset
    correctly.

    #4
    * src/cff/cfftypes.h (CFF_CharsetRec): Add `max_cid' member.
    * src/cff/cffload.c (cff_charset_load): Set `charset->max_cid'.
    * src/cff/cffgload.c (cff_slot_load): Change type of third parameter
    to `FT_UInt'.
    Check range of `glyph_index'.
    * src/cff/cffgload.h: Updated.

    #6
    * src/bdf/bdflib.c: fixed a problem with large encodings.
    Again, this patch comes from Debian libfreetype6 for 2.1.10 !
