Debian Bug     : 842043 842046 842361 842270

The libtiff library and associated tools provided in libtiff-tools are
vulnerable to many security problems.

This update drops many tools which are no longer supported upstream
and which are affected by multiple memory corruption issues:
* bmp2tiff (CVE-2016-3619, CVE-2016-3620, CVE-2016-3621, CVE-2016-5319,
            CVE-2015-8668)
* gif2tiff (CVE-2016-3186, CVE-2016-5102)
* ras2tiff
* sgi2tiff
* sgisv
* ycbcr
* rgb2ycbcr (CVE-2016-3623, CVE-2016-3624)
* thumbnail (CVE-2016-3631, CVE-2016-3632, CVE-2016-3633, CVE-2016-3634,
             CVE-2016-8331)

This update also fixes the following issues:

CVE-2014-8128, CVE-2015-7554, CVE-2016-5318

    Multiple buffer overflows triggered through TIFFGetField() on unknown
    tags. Lacking an upstream fix, the list of known tags has been
    extended to cover all those that are in use by the TIFF tools.

CVE-2016-5652

    Heap based buffer overflow in tiff2pdf.

CVE-2016-6223

    Information leak in 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 (reported by
    Mathias Svensson).

For Debian 7 "Wheezy", these problems have been fixed in version
4.0.2-6+deb7u7.

We recommend that you upgrade your tiff packages.
