+ + + +MAJOR CHANGES: + +

None + +

+ + +

+ + +CHANGES IN THE SOFTWARE CONFIGURATION: + +

Updated to use Automake 1.15 and Libtool 2.4.5 + +

+ +

+ + + +CHANGES IN LIBTIFF: + +

TIFFCheckDirOffset(): avoid uint16 overflow + when reading more than 65535 directories, and effectively error out when + eaching that limit. + +
TIFFNumberOfDirectories(): generate error in case of directory count + overflow. + +
TIFFAdvanceDirectory(): If nextdir is found to + be defective, then set it to zero before returning error in order + to terminate processing of truncated TIFF. + +
JPEG-in-TIFF: recognize SOF2, SOF9 and SOF10 + markers to avoid emitting a warning. Fix for compatibility with mozjpeg library. + Note: the default settings of mozjpeg will produce progressive scans, which + is forbidden by the TechNote. + +
JPEG-in-TIFF: Fix regression introduced in 3.9.3/4.0.0 that caused + all tiles/strips to include quantization tables even when the jpegtablesmode + had the JPEGTABLESMODE_QUANT bit set. + Also add explicit removal of Huffman tables when jpegtablesmode has the + JPEGTABLESMODE_HUFF bit set, which avoids Huffman tables to be emitted in the + first tile/strip (only useful in update scenarios. create-only was + fine) + +
JPEG-in-TIFF: fix segfault in JPEGFixupTagsSubsampling() on + corrupted image where tif->tif_dir.td_stripoffset == NULL. + (#2471) + +
NeXT codec: add new tests to check that we don't read outside of + the compressed input stream buffer. + +
NeXT codec: check that BitsPerSample = 2. Fixes + #2487 (CVE-2014-8129) + +
NeXT codec: in the "run mode", use tilewidth for tiled images + instead of imagewidth to avoid crash + +
tif_getimage.c: in OJPEG case, fix checks on strile width/height + in the putcontig8bitYCbCr42tile, putcontig8bitYCbCr41tile and + putcontig8bitYCbCr21tile cases. + +
in TIFFDefaultDirectory(), reset any already existing + extented tags installed by user code through the extender mechaninm before + calling the extender callback (GDAL #5054) + +
Fix warnings about unused parameters. + +
Fix various typos in comments found by Debian lintian tool (GDAL #5756) + +
tif_getimage.c: avoid divide by zero on invalid YCbCr subsampling. + (#2235) + +
tif_dirread.c: In EstimateStripByteCounts(), check return code + of _TIFFFillStriles(). This solves crashing bug on corrupted + images generated by afl. + +
tif_read.c: fix several invalid comparisons of a uint64 value with + <= 0 by casting it to int64 first. This solves crashing bug on corrupted + images generated by afl. + +
TIFFSetField(): refuse to set negative values for + TIFFTAG_XRESOLUTION and TIFFTAG_YRESOLUTION that cause asserts when writing + the directory + +
TIFFReadDirectory(): refuse to read ColorMap or + TransferFunction if BitsPerSample has not yet been read, otherwise reading + it later will cause user code to crash if BitsPerSample > 1 + +
TIFFRGBAImageOK(): return FALSE if LOGLUV with + SamplesPerPixel != 3, or if CIELAB with SamplesPerPixel != 3 or BitsPerSample != 8 + +
tif_config.vc.h: no longer use "#define snprintf _snprintf" with + Visual Studio 2015 aka VC 14 aka MSVC 1900 + +
LZW codec: prevent potential null dereference of sp->dec_codetab in LZWPreDecode + (#2459) + +
TIFFReadBufferSetup(): avoid passing -1 size + to TIFFmalloc() if passed user buffer size is 0 + (#2459) + +
TIFFReadDirEntryOutputErr(): Incorrect + count for tag should be a warning rather than an error since + errors terminate processing. + +
tif_dirinfo.c (TIFFField) : Fix data type for TIFFTAG_GLOBALPARAMETERSIFD tag. + +
Add definitions for TIFF/EP CFARepeatPatternDim and CFAPattern tags + (#2457) + +
tif_codec.c, tif_dirinfo.c: Enlarge some fixed-size buffers that weren't + large enough, and eliminate substantially all uses of sprintf(buf, + ...) in favor of using snprintf(buf, sizeof(buf), ...) +
configure.ac: Improve pkg-config static linking by adding -lm to Libs.private when needed. + +
tif_write.c: tmsize_t related casting warning fixed for + 64bit linux. + +
tif_read.c: uint64/tmsize_t change for MSVC warnings. + (#2427) + +
Fix TIFFPrintDirectory's handling of + field_passcount fields: it had the TIFF_VARIABLE and + TIFF_VARIABLE2 cases backwards. + +
PixarLog codec: Improve previous patch for CVE-2012-4447 + (to enlarge tbuf for possible partial stride at end) so that + overflow in the integer addition is detected. + +
tif_{unix,vms,win32}.c (_TIFFmalloc): ANSI C does not + require malloc() to return NULL pointer if requested allocation + size is zero. Assure that _TIFFmalloc does. + +
tif_zip.c: Avoid crash on NULL error messages. + +

+ +

+ + + +CHANGES IN THE TOOLS: + +

tiff2pdf: Fis various crashes and memory buffer access errors (oCERT-2014-013). +
tiff2pdf: fix buffer overflow on some YCbCr JPEG compressed images. + (#2445) +
tiff2pdf: fix buffer overflow on YCbCr JPEG compressed image. + (#2443) +
tiff2pdf: check return code of TIFFGetField() when reading TIFFTAG_SAMPLESPERPIXEL +
tiff2pdf: fix crash due to invalid tile count. +
tiff2pdf: Detect invalid settings of BitsPerSample/SamplesPerPixel for CIELAB / ITULAB +
tiff2pdf: Assure that memory size calculations for + _TIFFmalloc() do not overflow the range of tmsize_t. +
tiff2pdf: Avoid crash when TIFFTAG_TRANSFERFUNCTION tag returns one channel, + with the other two channels set to NULL. +
tiff2pdf: close PDF file. (#2479) +
tiff2pdf: Preserve input file directory order when pages + are tagged with the same page number. +
tiff2pdf.c: terminate after failure of allocating ycbcr buffer + (#2449 CVE-2013-4232) +
tiff2pdf: Rewrite JPEG marker parsing in + t2p_process_jpeg_strip to be at least marginally competent. The + approach is still fundamentally flawed, but at least now it won't + stomp all over memory when given bogus input. Fixes CVE-2013-1960. +
tiffdump: Guard against arithmetic overflow when calculating allocation buffer sizes. +
tiffdump: fix crash due to overflow of entry count. +
tiffdump: Fix double-free bug. +

tiffdump: avoid passing a NULL pointer to read() if seek() failed before. + (#2459) +
tiff2bw: when Photometric=RGB, the utility only works if SamplesPerPixel = 3. Enforce that. + (#2485, CVE-2014-8127) +
pal2rgb, thumbnail: fix crash by disabling TIFFTAG_INKNAMES copying. + (#2484, CVE-2014-8127) +
thumbnail: fix out-of-buffer write. + (#2489, CVE-2014-8128) +
thumbnail, tiffcmp: only read/write TIFFTAG_GROUP3OPTIONS + or TIFFTAG_GROUP4OPTIONS if compression is COMPRESSION_CCITTFAX3 or + COMPRESSION_CCITTFAX4. + (#2493, CVE-2014-8128) +
tiffcp: fix crash when converting YCbCr JPEG-compressed to none. + (#2480) +
bmp2tiff: fix crash due to int overflow related to input BMP dimensions +
tiffcrop: fix crash due to invalid TileWidth/TileHeight +

thumbnail, tiffcrop: "fix" heap read over-run found with + Valgrind and Address Sanitizer on test suite +
fax2ps: check malloc()/realloc() result. (#2470) +
gif2tiff: apply patch for CVE-2013-4243. (#2451) +
gif2tiff: fix possible OOB write. (#2452, CVE-2013-4244) +
gif2tiff: Be more careful about corrupt or hostile input files (#2450, CVE-2013-4231) +
tiff2rgba: fix usage message in that zip was wrongly described +
tiffinfo: Default various values fetched with TIFFGetField() to avoid being uninitialized. +
tiff2ps: Fix bug in auto rotate option code. +
ppm2tiff: avoid zero size buffer vulnerability (CVE-2012-4564). + check the linebytes calculation too, get the max() calculation + straight, avoid redundant error messages, check for malloc + failure. +
tiffset: now supports a -u option to unset a tag. + (#2419) +
Fix warnings about unused parameters. +
rgb2ycbcr, tiff2bw, tiff2pdf, tiff2ps, tiffcrop, tiffdither : + Enlarge some fixed-size buffers that weren't + large enough, and eliminate substantially all uses of sprintf(buf, + ...) in favor of using snprintf(buf, sizeof(buf), ...), so as to + protect against overflow of fixed-size buffers. This responds in + particular to CVE-2013-1961 concerning overflow in tiff2pdf.c's + t2p_write_pdf_page(). +
html/man/tiff2ps.1.html, html/man/tiffcp.1.html, + html/man/tiffdither.1.html, man/tiff2ps.1, man/tiffcp.1, + man/tiffdither.1, tools/tiff2ps.c, tools/tiffcp.c, + tools/tiffdither.c: Sync tool usage printouts and man pages with + reality + +

+ +

+ + + +CHANGES IN THE CONTRIB AREA: + +

Fix warnings about variables set but not used. +
contrib/dbs/xtiff/xtiff.c: Enlarge some fixed-size buffers that weren't + large enough, and eliminate substantially all uses of sprintf(buf, + ...) in favor of using snprintf(buf, sizeof(buf), ...), so as to + protect against overflow of fixed-size buffers. +
