It's probably worth noting that although the bundled utilities are pretty buggy, there are also several bugs affecting the libtiff library itself that can be hit with afl if you clean up the utility-level bugs first; these affect ImageMagick and any tools that rely on libtiff to display untrusted images. I reported some privately to the maintainers few weeks ago (before your report, in fact), but haven't had a lot of success so far. There's at least one other person who did the same. /mz _______________________________________________ Sent through the Full Disclosure mailing list http://nmap.org/mailman/listinfo/fulldisclosure Web Archives & RSS: http://seclists.org/fulldisclosure/
