From: Jim Meyering <meyering@redhat.com>

Subject: md5sum, sha1sum, etc: handle invalid input (i.e., don't segfault)

* src/md5sum.c (bsd_split_3): Return right away if s_len == 0.
* tests/misc/md5sum (bsd-segv): New test for the above.
* tests/misc/sha1sum (bsd-segv): Likewise.
* NEWS: Mention the bug fix.
Reported by Cristian Cadar, Daniel Dunbar and Dawson Engler.
