Use CVE-2014-3956.
Note that the unpatched code (in, for example, 8.14.8) has this in
conf.c:
** Parameters:
** lowest -- first fd to arrange to be closed
** highest -- last fd + 1 to arrange to be closed
void sm_close_on_exec(highest, lowest)
but callers use arguments of highest=STDERR_FILENO+1 and
lowest=DtableSize, apparently a CWE-683 issue.
8.14.9 has "void sm_close_on_exec(lowest, highest)" instead.
