This corresponds to attempts to 147 allocate arrays that are too large. For an example, consider the 148 following code: 149 150 count = read_uint32_from_file(); array = malloc( sizeof ( Item ) * 151 count ); for ( nn = 0; nn < count; nn++ ) 152 array[nn] = read_item_from_file(); 153 154 If `count' is larger than `FT_UINT_MAX/sizeof(Item)', the 155 multiplication overflows, and the array allocated os smaller than 156 the data read from the file. In this case, the heap will be 157 trashed, and this can be used as a denial-of-service attack, or make 158 the engine crash later. 159 160 The FT_ARRAY_NEW and FT_ARRAY_RENEW macros now ensure that the new 161 count is no larger than `FT_INT_MAX/item_size', otherwise a new 162 error code `FT_Err_Array_Too_Large' will be returned. 163 164 Note that the memory debugger now works again when FT_DEBUG_MEMORY 165 is defined. FT_STRICT_ALIASING has disappeared; the corresponding 166 code is now the default. 167 168 169 * include/freetype/config/ftconfig.h (FT_BASE_DEF) [!__cplusplus]: 170 Don't use `extern'. 171 172 * include/freetype/fterrdef.h (FT_Err_Array_Too_Large): New error 173 code. 174 175 * include/freetype/internal/ftmemory.h (FT_DEBUG_INNER) 176 [FT_DEBUG_MEMORY]: New macro. 177 (ft_mem_realloc, ft_mem_qrealloc): Pass new object size count also. 178 (ft_mem_alloc_debug, ft_mem_qalloc_debug, ft_mem_realloc_debug, 179 ft_mem_qrealloc_debug, ft_mem_free_debug): Removed. 180 (FT_MEM_ALLOC, FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC, 181 FT_MEM_FREE): Redefine. 182 (FT_MEM_NEW_ARRAY, FT_MEM_RENEW_ARRAY, FT_MEM_QNEW_ARRAY, 183 FT_MEM_QRENEW_ARRAY): Redefine. 184 (FT_ALLOC_MULT, FT_REALLOC_MULT, FT_MEM_QALLOC_MULT, 185 FT_MEM_QREALLOC_MULT): New macros. Update callers where 186 appropriate. 187 (FT_MEM_SET_ERROR): Slightly redefine. 188 189 190 * src/base/ftdbgmem.c (_ft_debug_file, _ft_debug_lineno) 191 [FT_DEBUG_MEMORY]: New global variables, replacing... 192 (FT_MemTableRec) [FT_DEBUG_MEMORY]: Remove `filename' and 193 `line_no'. Update all callers. 194 (ft_mem_debug_alloc) [FT_DEBUG_MEMORY]: Avoid possible integer 195 overflow. 196 (ft_mem_alloc_debug, ft_mem_realloc_debug, ft_mem_qalloc_debug, 197 ft_mem_qrealloc_debug, ft_mem_free_debug): Removed. 198 199 * src/base/ftmac.c (read_lwfn): Catch integer overflow. 200 * src/base/ftrfork.c (raccess_guess_darwin_hfsplus): Ditto. 201 * src/base/ftutil.c: Remove special code for FT_STRICT_ALIASING. 202 (ft_mem_alloc, ft_mem_realloc, ft_mem_qrealloc): Rewrite. 203 204 205 * include/freetype/ftstream.h (FT_FRAME_ENTER, FT_FRAME_EXIT, 206 FT_FRAME_EXTRACT, FT_FRAME_RELEASE): Use FT_DEBUG_INNER to report the 207 place where the frames were entered, extracted, exited or released 208 in the memory debugger. 209 210 * src/base/ftstream.c (FT_Stream_ReleaseFrame) [FT_DEBUG_MEMORY]: 211 Call ft_mem_free. 212 (FT_Stream_EnterFrame) [FT_DEBUG_MEMORY]: Use ft_mem_qalloc. 213 (FT_Stream_ExitFrame) [FT_DEBUG_MEMORY]: Use ft_mem_free. 214 215 2006-04-30 suzuki toshiya <mpsuzuki (a] hiroshima-u.ac.jp> 216 217 * src/base/ftobjs.c (Mac_Read_POST_Resource): Correct pfb_pos 218 initialization, remove extra cast to copy to pfb_lenpos. This fixes 219 parsing of PFB fonts with MacOS resource fork (bug introduced 220 2003-09-11).

Note that the 833 cache sub-system cannot be fully retrofitted, unfortunately. 834 835 * include/freetype/config/ftoption.h 836 (FT_CONFIG_OPTION_OLD_INTERNALS): New macro. 837 838 * include/freetype/ftcache.h, include/freetype/cache/ftccache.h, 839 include/freetype/cache/ftccmap.h, 840 include/freetype/internal/ftcalc.h, 841 include/freetype/internal/ftdriver.h, 842 include/freetype/internal/ftmemory.h, 843 include/freetype/internal/ftobjs.h, 844 include/freetype/internal/psaux.h, include/freetype/internal/sfnt.h, 845 include/freetype/internal/t1types.h, 846 include/freetype/internal/tttypes.h, src/base/ftcalc.c, 847 src/base/ftdbgmem.c, src/base/ftobjs.c, src/base/ftutil.c, 848 src/bdf/bdfdrivr.c, src/cache/ftccache.c, src/cache/ftccback.h, 849 src/cache/ftcmanag.c, src/cff/cffdrivr.c, src/cid/cidriver.c, 850 src/pcf/pcfdrivr.c, src/pfr/pfrdrivr.c, src/psaux/psauxmod.c, 851 src/sfnt/sfdriver.c, src/truetype/ttdriver.c, src/type1/t1driver.c, 852 src/type1/t1objs.c, src/type42/t42drivr.c, src/winfonts/winfnt.c: 853 Use FT_CONFIG_OPTION_OLD_INTERNALS to revive old functions and data 854 structures. 855 856 Move newly added structure elements to the end of the affected 857 structure and add stub fields (if FT_CONFIG_OPTION_OLD_INTERNALS is 858 defined) to assure binary compatibility with older FreeType 859 versions. 860 Use FT_CONFIG_OPTION_OLD_INTERNALS to add function stubs for old 861 functions: 862 863 ft_stub_set_char_sizes 864 ft_stub_set_pixel_sizes 865 866 Rename the following internal functions to provide the old function 867 names as stubs: 868 869 FT_Alloc -> ft_mem_alloc 870 FT_QAlloc -> ft_mem_qalloc 871 FT_Realloc -> ft_mem_realloc 872 FT_QRealloc -> ft_mem_qrealloc 873 FT_Free -> ft_mem_free 874 FT_Alloc_Debug -> ft_mem_alloc_debug 875 FT_QAlloc_Debug -> ft_mem_qalloc_debug 876 FT_Realloc_Debug -> ft_mem_realloc_debug 877 FT_QRealloc_Debug -> ft_mem_qrealloc_debug 878 FT_Free_Debug -> ft_mem_free_debug 879 880 2006-02-15 Chia-I Wu <b90201047 (a] ntu.edu.tw> 881 882 * include/freetype/internal/ftobjs.h (FT_Face_InternalRec): Remove 883 unused `max_points' and `max_contours'. 884 885 * src/cid/cidobjs.c (cid_face_init), src/type1/t1objs.c 886 (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Update. 887 888 * include/freetype/internal/tttypes.h (TT_FaceRec): Remove unused 889 `max_components'. 890 891 * src/truetype/ttinterp.h (TT_ExecContextRec): Remove unused 892 `loadSize' and `loadStack'. 893 894 * src/truetype/ttinterp.c (TT_Done_Context, TT_Load_Context), 895 src/sfnt/ttload.c (tt_face_load_maxp): Update. 896 897 * src/cff/cffobjs.h (cff_size_select), src/sfnt/sfdriver.c 898 (sfnt_interface), src/truetype/ttdriver.c (tt_size_request): Fix 899 compiler errors/warnings when TT_CONFIG_OPTION_EMBEDDED_BITMAPS is not 900 defined. 901 902 * src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Fix 903 possible segment faults for the non-FT_OPTIMIZE_MEMORY'ed versions. 904 (finally!) 905 906 907 For most OpenType tables, `tt_face_load_xxxx' simply loads the table 908 and `face->root' is set later in `sfnt_load_face'. Here, we try to 909 make this work for _all_ tables. Also improve tracing messages. 910 911 * src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c, 912 src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and 913 then exit. Error handling or setting face->root is done later in 914 `sfnt_load_face'. 915 916 * src/sfnt/sfobjs.c (sfnt_load_face): Work harder. 917 Mac bitmap-only fonts are not scalable. 918 Check that `face->header.Units_Per_EM' is not zero. 919 (LOAD_, LOADM_): Emit pretty trace messages. 920 921 * src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Read metrics 922 from `eblc'. 923 924 * src/sfnt/ttcmap.c (tt_face_build_cmaps), src/sfnt/ttpost.c 925 (load_format_20, load_format_25, tt_face_get_ps_name): Use 926 face->max_profile.numGlyphs, instead of face->root.num_glyphs. 927 928 2006-02-14 Werner Lemberg <wl (a] gnu.org> 929 930 * include/freetype/ftoutln.h (FT_Outline_Embolden): Mention in 931 documentation that negative strength values are possible. 932 Give an example call. 933 934 * include/freetype/freetype.h (FT_GlyphSlotRec): Improve 935 documentation of `outline' field. 936 937 * src/sfnt/sfobjs.c: Include FT_INTERNAL_DEBUG_H. 938 * src/sfnt/sfdriver.c: Include ttmtx.h. 939 940 * src/autofit/afcjk.c: Include aftypes.h and aflatin.h. 941 942 2006-02-14 Chia-I Wu <b90201047 (a] ntu.edu.tw> 943 944 * src/sfnt/ttmtx.c (tt_face_get_metrics): Typo. 945 946 2006-02-14 Chia-I Wu <b90201047 (a] ntu.edu.tw> 947 948 * src/sfnt/ttmtx.c (tt_face_load_hhea, tt_face_load_hmtx): Simply 949 return error if table is missing. 950 Check table length in non-FT_OPTIMIZE_MEMORY'ed `tt_face_load_hmtx'. 951 952 * src/sfnt/sfobjs.c (sfnt_load_face): Take care of missing metrics 953 tables. The last change makes Mac bitmap-only font not load and 954 this fixes it. 955 956 * src/truetype/ttgload.c (load_truetype_glyph): Fix compilation 957 error when FT_CONFIG_OPTION_INCREMENTAL is defined. 958 959 2006-02-13 Chia-I Wu <b90201047 (a] ntu.edu.tw> 960 961 Clean up the SFNT_Interface. In this final pass, `load_hmtx' is 962 split from `load_hhea'. 963 964 * include/freetype/internal/sfnt.h, src/sfnt/sfdriver.c, 965 src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Split `hmtx' from `hhea'. 966 967 * src/sfnt/sfobjs.c (sfnt_load_face): Update. 968 969 2006-02-13 Chia-I Wu <b90201047 (a] ntu.edu.tw> 970 971 * src/sfnt/ttmtx.h, src/sfnt/ttmtx.c: Why are there two copies of 972 code... 973 974 2006-02-13 Chia-I Wu <b90201047 (a] ntu.edu.tw> 975 976 Clean up the SFNT_Interface. In this pass, we want to treat the 977 font directory (offset table and table directory) as a normal table 978 like the others. This also means that TTCs are no longer recognized 979 there but in `init_face'. 980 981 * include/freetype/internal/sfnt.h (SFNT_Interface), 982 src/sfnt/sfdriver.c: `load_sfnt_header' and `load_directory' are 983 combined and renamed to `load_font_dir'. 984 985 * src/sfnt/ttload.h, src/sfnt/ttload.c: 986 s/sfnt_dir_check/check_table_dir/. 987 `sfnt_init' is moved to sfobjs.c and renamed to `sfnt_open_font'. 988 `tt_face_load_sfnt_header' and `tt_face_load_directory' are combined 989 and renamed to `tt_face_load_font_dir'. 990 991 * src/sfnt/sfobjs.c (sfnt_init_face): Recognize TTC here. 992 993 2006-02-13 Chia-I Wu <b90201047 (a] ntu.edu.tw> 994 995 Clean up the SFNT_Interface. Table loading functions are now named 996 after the tables' tags; `hdmx' is TrueType-specific and thus the 997 code is moved to the truetype module; `get_metrics' is moved here 998 from the truetype module so that the code can be shared with the cff 999 module. 1000 1001 This pass involves no real changes. That is, the code is moved 1002 verbatim mostly. The only exception is the return value of 1003 `tt_face_get_metrics'. 1004 1005 * include/freetype/internal/sfnt.h, src/sfnt/rules.mk, 1006 src/sfnt/sfdriver.c, src/sfnt/sfnt.c, src/sfnt/sfobjs.c, 1007 src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttsbit.c, 1008 src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: Clean up the SFNT_Interface. 1009 1010 * src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: New files. Metrics-related 1011 tables' loading and parsing code is moved to here. 1012 Move `tt_face_get_metrics' here from the truetype module. The 1013 return value is changed from `void' to `FT_Error'. 1014 1015 * include/freetype/internal/fttrace.h: New trace: ttmtx. 1016 1017 * src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and 1018 parsing code is moved here. 1019 New function `tt_face_load_prep' split from `tt_face_load_fpgm'. 1020 `tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist. 1021 1022 * src/cff/cffgload.c, src/cff/cffobjs.c: Update. 1023 1024 * src/truetype/ttgload.c, src/truetype/ttobjs.c: Update. 1025 1026 2006-02-11 Chia-I Wu <b90201047 (a] ntu.edu.tw> 1027 1028 * src/autofit/afcjk.c (af_cjk_metrics_init): Fix a stupid bug... 1029 1030 * src/autofit/aflatin.c (af_latin_metrics_init_widths): Use 1031 AF_LatinMetricsRec as the dummy metrics because we cast the metrics 1032 to it later in `af_latin_hints_link_segments'. 1033 1034 2006-02-11 Chia-I Wu <b90201047 (a] ntu.edu.tw> 1035 1036 * include/freetype/config/ftoption.h (AF_CONFIG_OPTION_CJK): #define 1037 to enable autofit CJK script support.

You need to #define AF_MOD_CJK in afcjk.c to enable it. 1054 1055 * src/autofit/afglobal.c, src/autofit/afcjk.h, src/autofit/afcjk.c, 1056 src/autofit/rules.mk, src/autofit/autofit.c, src/autofit/aftypes.h: 1057 Add CJK module based on akito's autohint patch. 1058 1059 * src/autofit/afhints.h (AF_SegmentRec): New field `len' for the 1060 overlap length of the segments. 1061 (AF_SEGMENT_LEN, AF_SEGMENT_DIST): New macros. 1062 1063 * src/autofit/aflatin.h (af_latin_metrics_init_widths), 1064 src/autofit/aflatin.c (af_latin_metrics_init_widths): Made 1065 `FT_LOCAL'. 1066 Use the character given by the caller. 1067 (af_latin_metrics_init_widths, af_latin_hints_link_segments): Scale 1068 the thresholds. 1069 1070 * src/autofit/afloader.c (af_loader_load_g): Respect 1071 AF_SCALER_FLAG_NO_ADVANCE. 1072 1073 2006-02-09 Werner Lemberg <wl (a] gnu.org> 1074 1075 * src/cid/cidparse.c (cid_parse_new): Remove shadowing variable. 1076 1077 2006-02-09 suzuki toshiya <mpsuzuki (a] hiroshima-u.ac.jp> 1078 1079 * src/cid/cidparse.c (cid_parse_new): Fix for abnormally short or 1080 broken CIDFont. Reported by Taek Kwan(TK) Lee (see ft-devel 1081 2005-11-02). 1082 1083 2006-02-08 suzuki toshiya <mpsuzuki (a] hiroshima-u.ac.jp> 1084 1085 * builds/unix/configure.ac: Fix bug for `--with-old-mac-fonts' 1086 option on UNIX platform. It has been broken since 2006-01-11. 1087 1088 2006-02-01 Werner Lemberg <wl (a] gnu.org> 1089 1090 * src/otvalid/module.mk: s/otvalid_module_class/otv_module_class/. 1091 * src/gxvalid/module.mk: s/gxvalid_module_class/gxv_module_class/. 1092 1093 * builds/unix/unixddef.mk: Actually do define PLATFORM (fixing 1094 change from 2006-01-31). 1095 (TOP_DIR, OBJ_DIR): Update. 1096 1097 * builds/unix/install.mk (install): Fix path for ftmodule.h. 1098 1099 * Makefile, *.mk, builds/unix/unix-cc.in, builds/unix-def.in: Use 1100 `?=' where appropriate. 1101 1102 * builds/detect.mk (TOP_DIR), builds/os2/os2-dev.mk (TOP_DIR), 1103 builds/win32/w32-dev.mk (TOP_DIR): Removed. Defined elsewhere. 1104 1105 2006-01-31 Werner Lemberg <wl (a] gnu.org> 1106 1107 Implement new, simplified module selection. With GNU make it is now 1108 sufficient to modify a single file, `modules.cfg', to control the 1109 inclusion of modules and base extension files. 1110 1111 This change also fixes the creation of ftmodule.h; it now depends on 1112 `modules.cfg' and thus is rebuilt only if necessary. 1113 1114 Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the 1115 default location. 1116 1117 * modules.cfg: New file. 1118 1119 * builds/freetype.mk: Don't include `modules.mk'. 1120 Include all `rules.mk' files as specified in `modules.cfg'. 1121 (FTOPTION_FLAG, FTOPTION_H): New variables. 1122 (FT_CFLAGS): Add macro definition for FT_CONFIG_MODULES_H. 1123 Add FTOPTION_FLAG. 1124 ($(FT_INIT_OBJ)): Don't use FT_MODULE_LIST. 1125 (CONFIG_H): Add FTMODULE_H and FTOPTION_H. 1126 (INCLUDES): Add DEVEL_DIR. 1127 (INCLUDE_FLAGS, FTSYS_SRC, FTSYS_OBJ, FTDEBUG_SRC, FTDEBUG_OBJ, 1128 OBJ_M, OBJ_S): Use `:=', not `='. 1129 (remove_ftmodule_h): New phony target to delete `ftmodule.h'. 1130 (distclean): Add remove_ftmodule_h. 1131 1132 * builds/modules.mk: (MODULE_LIST): Removed. 1133 (make_module_list, clean_module_list): Replace targets 1134 with... 1135 (FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New 1136 variables. Reason for the change is that it is not possible to have 1137 a phony prerequisite which is run only if the target file must be 1138 rebuilt (phony prerequisites act like subroutines and are *always* 1139 executed). We only want to rebuild `ftmodule.h' if `module.cfg' is 1140 changed. 1141 Update all callers. 1142 ($FTMODULE_H)): Rule to create `ftmodule.h', depending on 1143 `modules.cfg'. 1144 1145 * builds/toplevel.mk: Rewrite and simplify module handling. 1146 (MODULES_CFG, FTMODULE_H): New variables. 1147 Include MODULES_CFG. 1148 (MODULES): New variable to include all `module.mk' and `rules.mk' 1149 files. We no longer use make's `wildcard' function for this. 1150 1151 * Makefile (USE_MODULES): Remove. Update all users. 1152 (OBJ_DIR): Define it here. 1153 1154 * src/*/module.mk: Change 1155 1156 make_module_list: foo 1157 foo: ... 1158 1159 to 1160 1161 FTMODULE_H_COMMANDS += FOO 1162 define FOO 1163 ... 1164 endef 1165 1166 in all files. `FTMODULE_H_COMMANDS' is used in `FTMODULE_H_CREATE'. 1167 1168 * src/base/rules.mk (BASE_EXT_SRC): Use BASE_EXTENSIONS. 1169 1170 * builds/unix/detect.mk (setup): Always execute `configure' script. 1171 (have_mk): Rename to... 1172 (have_Makefile): This. 1173 Don't use `strip' function. 1174 1175 * builds/unix/unix.mk: Include `install.mk' only if BUILD_PROJECT is 1176 defined. 1177 (have_mk): Don't use `strip' function. 1178 Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test 1179 accordingly). 1180 1181 * builds/unix/install.mk (install, uninstall): Handle `ftmodule.h'. 1182 1183 * builds/os2/os2-dev.mk, builds/unix/unix-dev.mk, 1184 builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define 1185 BUILD_DIR but DEVEL_DIR for development header files. 1186 1187 * builds/ansi/ansi-def.mk (TOP_DIR, OBJ_DIR), 1188 builds/beos/beos-def.mk (TOP_DIR, OBJ_DIR), builds/unix/unix-def.in 1189 (TOP_DIR, OBJ_DIR): Removed.
