Subject: [magick-developers] DICOM bug
Hi,.
I think I've found a bug in the DICOM reader. In the current 6.4.9-8,
coders/dcm.c has in sketch form:
unsigned long
index,
...
index=ReadBlobLSBShort(image)
then at line 3487:
if (signed_data == 1)
index-=32767;
I haven't reviewed the code, but it looks as though the intent is
to do the subtraction mod 2^16, so
if (signed_data == 1)
index = ((long)index - 32767) & 0xffff);
Glenn
