Changes:
 tiff (4.0.7-2) unstable; urgency=high
 .
   * Backport security fixes:
     - fix uint32 overflow in TIFFReadEncodedStrip() that caused an integer
       division by zero,
     - avoid uint32 underflow in cpDecodedStrips that can cause various
       issues, such as buffer overflows in the library,
     - fix heap-based buffer overflow on generation of PixarLog / LUV
       compressed files, with ColorMap, TransferFunction attached and nasty
       plays with bitspersample,
     - fix ChopUpSingleUncompressedStrip() in reading outside of the
       StripByCounts/StripOffsets arrays when using TIFFReadScanline()
       (closes: #846837),
     - make OJPEGDecode() early exit in case of failure in OJPEGPreDecode() to
       avoid a divide by zero, and potential other issues,
     - fix readContigStripsIntoBuffer() in -i (ignore) mode so that the
       output buffer is correctly incremented to avoid write outside bounds,
     - add 3 extra bytes at end of strip buffer in
       readSeparateStripsIntoBuffer() to avoid read outside of heap allocated
       buffer,
     - fix integer division by zero when BitsPerSample is missing
       (closes: #846838),
     - fix null pointer dereference in -r mode when the image has no
       StripByteCount tag,
     - avoid potential division by zero if BitsPerSamples tag is missing,
     - limit the return number of inks to SamplesPerPixel in
       TIFFGetField(, TIFFTAG_NUMBEROFINKS, ) , so that code that parses ink
       names doesn't go past the end of the buffer,
     - avoid another potential division by zero if BitsPerSamples tag is
       missing,
     - fix uint32 underflow/overflow that can cause heap-based buffer overflow,
     - replace assert( (bps % 8) == 0 ) by a non assert check.
   * Remove thumbnail and rgb2ycbcr documentations, these tools no longer
     present.
