Here is the required fix....
Problem:
a) struct passwd has the pw_name field as a char *.
b) At various places in the code, nouser may be specified as the pwd
structure. It initializes pw_name = "";
c) Line 558 we see the following;
strncpy(pwd->pw_name, utmp.ut_name, NMAX);
utmp.ut_name is setup properly in doremotelogin and will be more than
one character long.
Solution:
Allocate the space that is necessary.... (I left 9 spaces, but 8 will do
nicely).
