This avoids TIFFGetField() +to behave differently depending on whether the codec is enabled or not, and +thus can avoid stack based buffer overflows in a number of TIFF utilities +such as tiffsplit, tiffcmp, thumbnail, etc. +Patch derived from 0063-Handle-properly-CODEC-specific-tags.patch +(http://bugzilla.maptools.org/show_bug.cgi?id=2580) by Raphaël Hertzog. +Fixes: +http://bugzilla.maptools.org/show_bug.cgi?id=2580 +http://bugzilla.maptools.org/show_bug.cgi?id=2693 +http://bugzilla.maptools.org/show_bug.cgi?id=2625 (CVE-2016-10095) +http://bugzilla.maptools.org/show_bug.cgi?id=2564 (CVE-2015-7554) +http://bugzilla.maptools.org/show_bug.cgi?id=2561 (CVE-2016-5318) +http://bugzilla.maptools.org/show_bug.cgi?id=2499 (CVE-2014-8128) +http://bugzilla.maptools.org/show_bug.cgi?id=2441 +http://bugzilla.maptools.org/show_bug.cgi?id=2433 +Index: libtiff/libtiff/tif_dirread.c +=================================================================== +RCS file: /cvs/maptools/cvsroot/libtiff/libtiff/tif_dirread.c,v +retrieving revision 1.208 +retrieving revision 1.209 +diff -u -r1.208 -r1.209 +--- libtiff/libtiff/tif_dirread.c 27 Apr 2017 15:46:22 -0000 1.208 ++++ libtiff/libtiff/tif_dirread.c 1 Jun 2017 12:44:04 -0000 1.209 +@@ -1,4 +1,4 @@ +-/* $Id: tif_dirread.c,v 1.208 2017-04-27 15:46:22 erouault Exp $ */ ++/* $Id: tif_dirread.c,v 1.209 2017-06-01 12:44:04 erouault Exp $ */ + + /* + * Copyright (c) 1988-1997 Sam Leffler +@@ -3580,6 +3580,10 @@ + goto bad;
