Hence, following scenarios might happen +and trigger the NULL pointer dereference: + +(1) TIFF File of photometric type 4 or more has illegal Transfer + Function field. + +(2) TIFF File has photometric type 3 or less and defines a + SamplesPerPixel field such that SamplesPerPixel > Color Channels + without defining all extra samples in the ExtraSamples fields. + +In this patch, we address both issues with respect of the following +principles: + +(A) In the case of (1), the defined transfer table should be printed + safely even if it isn't 'legal'. This allows us to avoid expensive + checks in TIFFPrintDirectory. Also, it is quite possible that + an alternative photometric type would be developed (not part of the + standard) and would allow definition of Transfer Table. We want + libtiff to be able to handle this scenario out of the box. + +(B) In the case of (2), the transfer table should be printed at its + right size, that is if TIFF file has photometric type Palette + then the transfer table should have one row and not three, even + if two extra samples are declared. + +In order to fulfill (A) we simply add a new 'i < 3' end condition to +the broken TIFFPrintDirectory loop. This makes sure that in any case +where (b) would be respected but not (a), everything stays fine. + +(B) is fulfilled by the loop condition +'i < td->td_samplesperpixel - td->td_extrasamples'. This is enough as +long as (b) is respected. + +Naturally, we also make sure (b) is respected. This is done in the +TIFFReadDirectory function by making sure any non-color channel is +counted in ExtraSamples. + +This commit addresses CVE-2018-7456. +--- + libtiff/tif_dirread.c | 61 +++++++++++++++++++++++++++++++++++++++++++ + libtiff/tif_print.c | 2 +- + libtiff/tif_unix.c | 9 +++++++ + libtiff/tiffio.h | 1 + + 4 files changed, 72 insertions(+), 1 deletion(-) + +diff --git a/libtiff/tif_dirread.c b/libtiff/tif_dirread.c +index 0a9484d..8dc40b5 100644 +--- a/libtiff/tif_dirread.c ++++ b/libtiff/tif_dirread.c +@@ -65,6 +65,35 @@ static int TIFFFetchDoubleArray(TIFF*, TIFFDirEntry*, double*); + static int TIFFFetchAnyArray(TIFF*, TIFFDirEntry*, double*); + static int TIFFFetchShortPair(TIFF*, TIFFDirEntry*); + static void ChopUpSingleUncompressedStrip(TIFF*); ++static int _TIFFGetMaxColorChannels(uint16 photometric); ++ ++/* ++ * Return the maximum number of color channels specified for a given photometric ++ * type. 0 is returned if photometric type isn't supported or no default value ++ * is defined by the specification. ++ */ ++static int _TIFFGetMaxColorChannels( uint16 photometric ) ++{ ++ switch (photometric) { ++ case PHOTOMETRIC_PALETTE: ++ case PHOTOMETRIC_MINISWHITE: ++ case PHOTOMETRIC_MINISBLACK: ++ return 1; ++ case PHOTOMETRIC_YCBCR: ++ case PHOTOMETRIC_RGB: ++ case PHOTOMETRIC_CIELAB: ++ return 3; ++ case PHOTOMETRIC_SEPARATED: ++ case PHOTOMETRIC_MASK: ++ return 4; ++ case PHOTOMETRIC_LOGL: ++ case PHOTOMETRIC_LOGLUV: ++ case PHOTOMETRIC_ITULAB: ++ case PHOTOMETRIC_ICCLAB: ++ default: ++ return 0; ++ } ++} + + /* + * Read the next TIFF directory from a file and convert it to the internal +@@ -86,6 +115,7 @@ TIFFReadDirectory(TIFF* tif) + uint16 previous_tag = 0; + int diroutoforderwarning = 0, compressionknown = 0; + int haveunknowntags = 0; ++ int color_channels; + + tif->tif_diroff = tif->tif_nextdiroff; + /* +@@ -617,6 +647,37 @@ TIFFReadDirectory(TIFF* tif) + } + } + } ++ ++ /* ++ * Make sure all non-color channels are extrasamples. ++ * If it's not the case, define them as such. ++ */ ++ color_channels = _TIFFGetMaxColorChannels(tif->tif_dir.td_photometric); ++ if (color_channels && tif->tif_dir.td_samplesperpixel - tif->tif_dir.td_extrasamples > color_channels) { ++ uint16 old_extrasamples; ++ uint16 *new_sampleinfo; ++ ++ TIFFWarningExt(tif->tif_clientdata,module, "Sum of Photometric type-related " ++ "color channels and ExtraSamples doesn't match SamplesPerPixel.
