	* libtiff/tif_thunder.c: Correct potential buffer overflow with
	thunder encoded files with wrong bitspersample set.  The libtiff
	development team would like to thank Marin Barbella and TippingPoint's
	Zero Day Initiative for reporting this vulnerability (ZDI-CAN-1004,
	CVE-2011-1167).

	* libtiff/tif_fax3.h: Fix to last change allowing zero length
	runs at the start of a scanline - needed for legal cases.

2011-03-02  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_fax3.h: Protect against a fax VL(n) codeword commanding
	a move left.  Without this, a malicious input file can generate an
	indefinitely large series of runs without a0 ever reaching the right
	margin, thus overrunning our buffer of run lengths.  Per CVE-2011-0192.
	This is a modified version of a patch proposed by Drew Yao of Apple
	Product Security.  It adds an unexpected() report, and disallows the
	equality case, since emitting a run without increasing a0 still allows
	buffer overrun.

	* libtiff/tif_jpeg.c: avoid divide by zero in degenerate case (#2296)

	* tools/tiff2rgba.c: close source file on error to make leak
	detection easier.

	* libtiff/tif_getimage.c: avoid leaks if TIFFRGBAImageBegin() fails.

2011-02-22  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_lzma.c: Maintain tif_rawcc/tif_rawcp (CHUNKY_STRING_READ
	_SUPPORT)

2011-02-18  Frank Warmerdam  <warmerdam@pobox.com>

	* configure.ac, configure: Added support for --enable-chunky-strip-read
	configure option to enable the experimental feature from a couple
	months ago for reading big strips in chunks.

	* configure.ac, tif_read.c, tif_readdir.c, tif_dir.h, tiffiop.h,
	tif_write.c, tif_print.c, tif_jpeg.c, tif_dirwrite.c, tif_write.c:
	Implement optional support for deferring the load of strip/tile
	offset and size tags for optimized scanning of directories.  Enabled
	with the --enable-defer-strile-load configure option (DEFER_STRILE_LOAD
	#define in tif_config.h).

2011-02-11  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_print.c: remove unused variable.

2011-02-09  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_win32.c: avoid error/warning buffer overrun problem
	with non-console (popup message) builds on win32.

2011-01-24  Olivier Paquet  <olivier.paquet@gmail.com>

	* libtiff/{tif_dir.{h,c}, tif_dirinfo.c, tif_dirread.c, tif_dirwrite.c,
	tif_print.c, tiff.h, tiffiop.h} : Added support for
	TIFFTAG_SMINSAMPLEVALUE and TIFFTAG_SMAXSAMPLEVALUE to have different
	values for each sample. Presents the min/max of all samples by default for
	compatibility. TIFFSetField/TIFFGetField can be made to handle those tags
	as arrays by changing the new TIFFTAG_PERSAMPLE pseudo tag.

2011-01-06  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_pixarlog.c: Note that tif_rawcc/tif_rawcp are not
	maintained.

	* libtiff/tif_zip.c: Maintain tif_rawcc/tif_rawcp when decoding
	for CHUNKY_STRIP_READ_SUPPORT.

	* libtiff/tif_jpeg.c: ensure that rawcc and rawcp are maintained
	during JPEGPreDecode and JPEGDecode calls.
	* libtiff/tif_read.c: larger read ahead for CHUNKY_STRIP_READ_SUPPORT,
	as compression formats like JPEG keep 16 lines interleaved in a sense
	and might need to touch	quite a bit of data.

2011-01-03  Lee Howard <faxguy@howardsilvan.com>

	* libtiff/tif_jpeg.c: Fix regressions with 2 and 3 band images
	caused by commit on 2010-12-14.  Submitted by e-mail from
	Even Rouault <even.rouault@mines-paris.org>

2010-12-31  Olivier Paquet  <olivier.paquet@gmail.com>

	* libtiff/tif_dirwrite.c: Fixed writing of TIFFTAG_REFERENCEBLACKWHITE.

2010-12-23  Andrey Kiselev  <dron@ak4719.spb.edu>

	* tools/tiffcp.c, man/tiffcp.1: Added support for specifying the
	compression level parameter (preset) for Deflate and LZMA encoders,
	e.g "-c lzma:p1" or "-c zip:p9".

	* libtiff/tif_lzma.c: Properly set the LZMA2 compression level
	(preset) in LZMAVSetField().

2010-12-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtiff/Makefile.am (libtiff_la_SOURCES): Added tif_lzma.c to
	Makefile.

2010-12-14  Andrey Kiselev  <dron@ak4719.spb.edu>

	* configure.ac, libtiff/{tif_codec.c, tif_config.h.in, tiff.h,
	tiffiop.h, tif_lzma.c}, tools/tiffcp.c, man/tiffcp.1: Implement a new
	TIFF compression scheme LZMA reserving a new value 34925 for
	Compression tag. As per
