Out-of-bounds read/write was reported in tiff2pdf libtiff tool: - <a href="https://access.redhat.com/security/cve/CVE-2014-8129">CVE-2014-8129</a> libtiff: Out-of-bounds Read &amp; Write in the tiff2pdf tool <a href="http://bugzilla.maptools.org/show_bug.cgi?id=2487">http://bugzilla.maptools.org/show_bug.cgi?id=2487</a> - <a href="https://access.redhat.com/security/cve/CVE-2014-8129">CVE-2014-8129</a> libtiff: Out-of-bounds Read &amp; Write in the tiff2pdf tool <a href="http://bugzilla.maptools.org/show_bug.cgi?id=2488">http://bugzilla.maptools.org/show_bug.cgi?id=2488</a> Above upstream bugs were fixed by the below commits: 2014-12-21 Even Rouault &lt;even.rouault&gt; * libtiff/tif_next.c: check that BitsPerSample = 2. Fixes <a href="http://bugzilla.maptools.org/show_bug.cgi?id=2487">http://bugzilla.maptools.org/show_bug.cgi?id=2487</a> (<a href="https://access.redhat.com/security/cve/CVE-2014-8129">CVE-2014-8129</a>) 2014-12-21 Even Rouault &lt;even.rouault&gt; Fix various crasher bugs on fuzzed images. * libtiff/tif_dir.c: TIFFSetField(): refuse to set negative values for TIFFTAG_XRESOLUTION and TIFFTAG_YRESOLUTION that cause asserts when writing the directory * libtiff/tif_dirread.c: 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 &gt; 1 * libtiff/tif_getimage.c: TIFFRGBAImageOK(): return FALSE if LOGLUV with SamplesPerPixel != 3, or if CIELAB with SamplesPerPixel != 3 or BitsPerSample != 8 * libtiff/tif_next.c: in the "run mode", use tilewidth for tiled images instead of imagewidth to avoid crash * tools/bmp2tiff.c: fix crash due to int overflow related to input BMP dimensions * tools/tiff2pdf.c: fix crash due to invalid tile count (should likely be checked by libtiff too). Detect invalid settings of BitsPerSample/SamplesPerPixel for CIELAB / ITULAB * tools/tiffcrop.c: fix crash due to invalid TileWidth/TileHeight * tools/tiffdump.c: fix crash due to overflow of entry count.
