  • Overread Buffers
    An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

  • NASL family SuSE Local Security Checks
    NASL id OPENSUSE-2016-1425.NASL
    description Tiff was updated to version 4.0.7. This update fixes the following issues : - libtiff/tif_aux.c + Fix crash in TIFFVGetFieldDefaulted() when requesting Predictor tag and that the zip/lzw codec is not configured. (http://bugzilla.maptools.org/show_bug.cgi?id=2591) - libtiff/tif_compress.c + Make TIFFNoDecode() return 0 to indicate an error and make upper level read routines treat it accordingly. (http://bugzilla.maptools.org/show_bug.cgi?id=2517) - libtiff/tif_dir.c + Discard values of SMinSampleValue and 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. (CVE-2014-8127, boo#914890, duplicate: CVE-2016-3658, boo#974840) - libtiff/tif_dirread.c + In TIFFFetchNormalTag(), do not dereference NULL pointer when values of tags with TIFF_SETGET_C16_ASCII/TIFF_SETGET_C32_ASCII access are 0-byte arrays. (CVE-2016-9448, boo#1011103) + In TIFFFetchNormalTag(), make sure that values of tags with TIFF_SETGET_C16_ASCII/TIFF_SETGET_C32_ASCII access are null terminated, to avoid potential read outside buffer in _TIFFPrintField(). (CVE-2016-9297, boo#1010161) + Prevent reading ColorMap or TransferFunction if BitsPerPixel > 24, so as to avoid huge memory allocation and file read attempts + Reject images with OJPEG compression that have no TileOffsets/StripOffsets tag, when OJPEG compression is disabled. Prevent NULL pointer dereference in TIFFReadRawStrip1() and other functions that expect td_stripbytecount to be non NULL. (http://bugzilla.maptools.org/show_bug.cgi?id=2585) + When compiled with DEFER_STRILE_LOAD, fix regression, when reading a one-strip file without a StripByteCounts tag. + Workaround false positive warning of Clang Static Analyzer about NULL pointer dereference in TIFFCheckDirOffset(). - libtiff/tif_dirwrite.c + Avoid NULL pointer dereference on td_stripoffset when writing directory, if FIELD_STRIPOFFSETS was artificially set for a hack case in OJPEG case. Fixes (CVE-2014-8127, boo#914890, duplicate: CVE-2016-3658, boo#974840) + Fix truncation to 32 bit of file offsets in TIFFLinkDirectory() and TIFFWriteDirectorySec() when aligning directory offsets on an even offset (affects BigTIFF). - libtiff/tif_dumpmode.c + DumpModeEncode() should return 0 in case of failure so that the above mentionned functions detect the error. - libtiff/tif_fax3.c + remove dead assignment in Fax3PutEOLgdal(). - libtiff/tif_fax3.h + make Param member of TIFFFaxTabEnt structure a uint16 to reduce size of the binary. - libtiff/tif_getimage.c + Fix out-of-bound reads in TIFFRGBAImage interface in case of unsupported values of SamplesPerPixel/ExtraSamples for LogLUV/CIELab. Add explicit call to TIFFRGBAImageOK() in TIFFRGBAImageBegin(). Fix CVE-2015-8665 and CVE-2015-8683. + TIFFRGBAImageOK: Reject attempts to read floating point images. - libtiff/tif_luv.c + Fix potential out-of-bound writes in decode functions in non debug builds by replacing assert()s by regular if checks (http://bugzilla.maptools.org/show_bug.cgi?id=2522). Fix potential out-of-bound reads in case of short input data. + Validate that for COMPRESSION_SGILOG and PHOTOMETRIC_LOGL, there is only one sample per pixel. Avoid potential invalid memory write on corrupted/unexpected images when using the TIFFRGBAImageBegin() interface - libtiff/tif_next.c + Fix potential out-of-bound write in NeXTDecode() (http://bugzilla.maptools.org/show_bug.cgi?id=2508) - libtiff/tif_pixarlog.c + Avoid zlib error messages to pass a NULL string to %s formatter, which is undefined behaviour in sprintf(). + Fix out-of-bounds write vulnerabilities in heap allocated buffers. Reported as MSVR 35094. + Fix potential buffer write overrun in PixarLogDecode() on corrupted/unexpected images (CVE-2016-5875, boo#987351) - libtiff/tif_predict.c + PredictorSetup: Enforce bits-per-sample requirements of floating point predictor (3). (CVE-2016-3622, boo#974449) - libtiff/tif_predict.h, libtiff/tif_predict.c + 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. - libtiff/tif_read.c + Fix out-of-bounds read on memory-mapped files in TIFFReadRawStrip1() and TIFFReadRawTile1() when stripoffset is beyond tmsize_t max value + Make TIFFReadEncodedStrip() and TIFFReadEncodedTile() directly use user provided buffer when no compression (and other conditions) to save a memcpy(). - libtiff/tif_strip.c + Make TIFFNumberOfStrips() return the td->td_nstrips value when it is non-zero, instead of recomputing it. This is needed in TIFF_STRIPCHOP mode where td_nstrips is modified. Fixes a read outsize of array in tiffsplit (or other utilities using TIFFNumberOfStrips()). (CVE-2016-9273, boo#1010163) - 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. + Make TIFFWriteEncodedStrip() and TIFFWriteEncodedTile() directly use user provided buffer when no compression to save a memcpy(). + TIFFWriteEncodedStrip() and TIFFWriteEncodedTile() should return -1 in case of failure of tif_encodestrip() as documented - tools/fax2tiff.c + Fix segfault when specifying -r without argument. (http://bugzilla.maptools.org/show_bug.cgi?id=2572) - tools/Makefile.am + The libtiff tools bmp2tiff, gif2tiff, ras2tiff, sgi2tiff, sgisv, and ycbcr are completely removed from the distribution. The libtiff tools rgb2ycbcr and thumbnail are only built in the build tree for testing. Old files are put in new 'archive' subdirectory of the source repository, but not in distribution archives. These changes are made in order to lessen the maintenance burden. - tools/tiff2bw.c + Fix weight computation that could result of color value overflow (no security implication). Fix http://bugzilla.maptools.org/show_bug.cgi?id=2550. - tools/tiff2pdf.c + Avoid undefined behaviour related to overlapping of source and destination buffer in memcpy() call in t2p_sample_rgbaa_to_rgb() (http://bugzilla.maptools.org/show_bug.cgi?id=2577) + Fix out-of-bounds write vulnerabilities in heap allocate buffer in t2p_process_jpeg_strip(). Reported as MSVR 35098. + Fix potential integer overflows on 32 bit builds in t2p_read_tiff_size() (http://bugzilla.maptools.org/show_bug.cgi?id=2576) + Fix read -largely- outsize of buffer in t2p_readwrite_pdf_image_tile(), causing crash, when reading a JPEG compressed image with TIFFTAG_JPEGTABLES length being one. (CVE-2016-9453, boo#1011107) + Fix write buffer overflow of 2 bytes on JPEG compressed images. Also prevents writing 2 extra uninitialized bytes to the file stream. (TALOS-CAN-0187, CVE-2016-5652, boo#1007280) - tools/tiffcp.c + Fix out-of-bounds write on tiled images with odd tile width vs image width. Reported as MSVR 35103. + Fix read of undefined variable in case of missing required tags. Found on test case of MSVR 35100. - tools/tiffcrop.c + Avoid access outside of stack allocated array on a tiled separate TIFF with more than 8 samples per pixel. (CVE-2016-5321, CVE-2016-5323, boo#984813, boo#984815) + Fix memory leak in (recent) error code path. + Fix multiple uint32 overflows in writeBufferToSeparateStrips(), writeBufferToContigTiles() and writeBufferToSeparateTiles() that could cause heap buffer overflows. (http://bugzilla.maptools.org/show_bug.cgi?id=2592) + Fix out-of-bound read of up to 3 bytes in readContigTilesIntoBuffer(). Reported as MSVR 35092. + Fix read of undefined buffer in readContigStripsIntoBuffer() due to uint16 overflow. Reported as MSVR 35100. + Fix various out-of-bounds write vulnerabilities in heap or stack allocated buffers. Reported as MSVR 35093, MSVR 35096 and MSVR 35097. + readContigTilesIntoBuffer: Fix signed/unsigned comparison warning. - tools/tiffdump.c + Fix a few misaligned 64-bit reads warned by -fsanitize + ReadDirectory: Remove uint32 cast to_TIFFmalloc() argument which resulted in Coverity report. Added more mutiplication overflow checks - tools/tiffinfo.c + Fix out-of-bound read on some tiled images. (http://bugzilla.maptools.org/show_bug.cgi?id=2517) + TIFFReadContigTileData: Fix signed/unsigned comparison warning. + TIFFReadSeparateTileData: Fix signed/unsigned comparison warning.

    description Multiple vulnerabilities have been discovered in the libtiff library and the included tools tiff2rgba, rgb2ycbcr, tiffcp, tiffcrop, tiff2pdf and tiffsplit, which may result in denial of service, memory disclosure or the execution of arbitrary code. There were additional vulnerabilities in the tools bmp2tiff, gif2tiff, thumbnail and ras2tiff, but since these were addressed by the libtiff developers by removing the tools altogether, no patches are available and those tools were also removed from the tiff package in Debian stable. The change had already been made in Debian stretch before and no applications included in Debian are known to rely on these scripts. If you use those tools in custom setups, consider using a different conversion/thumbnailing tool.
