The place of Out of bound read:
|
|
|
|
ret_val = 0;
|
|
for (i = 0; i < td->td_customValueCount; i++) {
|
|
TIFFTagValue *tv = td->td_customValues + i;
|
|
|
|
if (tv->info->field_tag != tag)
|
|
continue;

The place of Out of bound read:
|
|
|
|
The 1072 line of tif_dir.c
|
|
|
|
1068 ret_val = 0;
|
|
1069 for (i = 0; i < td->td_customValueCount; i++) {
|
|
1070 TIFFTagValue *tv = td->td_customValues + i;
|
|
1071
|
|
1072 if (tv->info->field_tag != tag)
|
|
1073 continue;
|
|
|
|
As tv increased in 1070, Out of bound read happened in 1072 when the pointer tv
|
|
was referenced.
