The format string passed to alloc_rootdir_entry results in sprintf overflowing de->name, writing the trailing null byte to de->ext (check.c:177). This might have been the author's intention, but _FORTIFY_SOURCE=2 does not allow such behaviour, terminating the program.
A patch for this issue is available on the Red Hat bugtracker [1], where Jaroslav mentions having sent the patch upstream on 2011-02-01. Regardless, the patch doesn't seem to have made its way into a dosfstools release. (The Debian maintainer appears to be the dosfstools author - please have a look at aforementioned Red Hat bug report) Joerie [1]: https://bugzilla.redhat.com/show_bug.cgi?id=674095 -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
