commit 40448d58fbfad52d2dde5bd18daa30b17fe35fcd
Author: erouault <erouault>
Date: Thu Jun 1 12:44:04 2017 +0000
* libtiff/tif_dirinfo.c, tif_dirread.c: add _TIFFCheckFieldIsValidForCodec(),
and use it in TIFFReadDirectory() so as to ignore fields whose tag is a
codec-specified tag but this codec is not enabled. This avoids TIFFGetField()
to behave differently depending on whether the codec is enabled or not, and
thus can avoid stack based buffer overflows in a number of TIFF utilities
such as tiffsplit, tiffcmp, thumbnail, etc.

Subject: [PATCH] * libtiff/tif_read.c, tiffiop.h: add a
_TIFFReadEncodedStripAndAllocBuffer() function, variant of
TIFFReadEncodedStrip() that allocates the decoded buffer only after a first
successful TIFFFillStrip(). This avoids excessive memory allocation on
corrupted files. * libtiff/tif_getimage.c: use
_TIFFReadEncodedStripAndAllocBuffer(). Fixes
