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.
