#352 TIFF heap corruption

[Jorge Diogo]

The attached tiff-bug-mac.tiff image corrupts the memory heap, when loaded in MSVC compiled Windows executable, with the 3.19.0-2021 and 3.18 versions of FreeImage.

The same image, when saved from Photoshop in "IBM PC" byte order (also attached: tiff-no-bug-pc.tif) doesn't corrupt memory.

The error is triggered inside:
tiff_read_exif_profile >
TIFFReadEXIFDirectory >
TIFFReadCustomDirectory >
TIFFFreeDirectory

I confirm this patch fixed the problem with these TIFF files - the previously reported bug #346.
Thank you so much @toxie!
