| | | | | | | | Replace assertions by runtime checks to avoid assertions in debug mode, or buffer overflows in release mode. Can happen when dealing with unusual tile size like YCbCr with subsampling. Reported as MSVR 35105 by Axel Souchet & Vishal Chauhan from the MSRC Vulnerabilities & Mitigations team.

* * libtiff/tif_dir.c: discard values of SMinSampleValue anderouault2016-10-253-4/+57
| | | | | | | | | | | | | | | | | | SMaxSampleValue when they have been read and the value of SamplesPerPixel is changed afterwards (like when reading a OJPEG compressed image with a missing SamplesPerPixel tag, and whose photometric is RGB or YCbCr, forcing SamplesPerPixel being 3). Otherwise when rewriting the directory (for example with tiffset, we will expect 3 values whereas the array had been allocated with just one), thus causing a out of bound read access. Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2500 (CVE-2014-8127, duplicate: CVE-2016-3658) * libtiff/tif_write.c: avoid null pointer dereference on td_stripoffset when writing directory, if FIELD_STRIPOFFSETS was artificially set for a hack case in OJPEG case.

| | | | | | | t2p_readwrite_pdf_image_tile(), causing crash, when reading a JPEG compressed image with TIFFTAG_JPEGTABLES length being one. Reported as MSVR 35101 by Axel Souchet and Vishal Chauhan from the MSRC Vulnerabilities & Mitigations team.

Probably not a security issue but I can be wrong. Reported as MSVR 35100 by Axel Souchet from the MSRC Vulnerabilities & Mitigations team.

Discovered by Axel Souchet and Vishal Chauhan from the MSRC Vulnerabilities & Mitigations team. * tools/tiff2pdf.c: fix out-of-bounds write vulnerabilities in heap allocate buffer in t2p_process_jpeg_strip(). Reported as MSVR 35098. Discovered by Axel Souchet and Vishal Chauhan from the MSRC Vulnerabilities & Mitigations team. * libtiff/tif_pixarlog.c: fix out-of-bounds write vulnerabilities in heap allocated buffers. Reported as MSVR 35094. Discovered by Axel Souchet and Vishal Chauhan from the MSRC Vulnerabilities & Mitigations team. * libtiff/tif_write.c: fix issue in error code path of TIFFFlushData1() that didn't reset the tif_rawcc and tif_rawcp members. I'm not completely sure if that could happen in practice outside of the odd behaviour of t2p_seekproc() of tiff2pdf). The report points that a better fix could be to check the return value of TIFFFlushData1() in places where it isn't done currently, but it seems this patch is enough. Reported as MSVR 35095. Discovered by Axel Souchet & Vishal Chauhan & Suha Can from the MSRC Vulnerabilities & Mitigations team.
