Summary:                    telnetd segfault when using devpts and /dev/pts is
not mounted
Description: 
In telnetd.c:getpty(), the return value of ptsname() is passed to strcpy()
without a check, while it is documented as returning NULL on error.  This
happens for example if the kernel was compiled with UNIX98 PTY support (so
openning /dev/ptmx works), and /dev/pts is not mounted.
