Subject: Check tiff/exif parsing code for IFD loop handling
Date: Sun, 31 Jul 2011 13:06:41 +1000
To: bug-Imager [...] rt.cpan.org
From: tonyc [...] cpan.org
I suspect libtiff has a check for loops. IIRC, the jpeg exif code only looks at the first IFD, so it should be safe too. But it needs: a) a review b) tests

Switched to TIFFReadDirectory() instead of TIFFSetDirectory() since that checks for loops. The EXIF code doesn't loop through IFDs.
