gets() does not define the buffer size, so it can be overflooded.

also the same. from the man:
BUGS
       Never use mktemp(). Some implementations follow  BSD  4.3  and  replace
       XXXXXX  by  the current process id and a single letter, so that at most
       26 different names can be returned.  Since on the one  hand  the  names
       are  easy to guess, and on the other hand there is a race between test-
       ing whether the name exists and opening the file, every use of mktemp()
       is a security risk.  The race is avoided by mkstemp(3).
