- More information:
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)
- 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 /
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.
Heap based buffer overflow in tiff2pdf.
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.
