Message-ID: <549889EC.8030700@gmail.com> Date: Mon, 22 Dec 2014 23:15:24 +0200 From: Paris Zoumpouloglou <pariszoump@...il.com> To: fulldisclosure@...lists.org Subject: Re: [FD] CVE-2014-9330: Libtiff integer overflow in bmp2tiff It's true utilities are pretty buggy. I've stumbled upon many duplicate bugs in the tracker, probably because of all the afl action :) What is also worth noting (I didn't notice at first) is that the latest available stable source code of libtiff (found here http://download.osgeo.org/libtiff/) hasn't been updated since 2012. Since then many bugs have been reported which have been fixed in the CVS repo and distribution packages but no one has changed the the archives.
