Examining data/proftpd-mod-msg-0.5/mod_msg.c

FINAL RESULTS:

data/proftpd-mod-msg-0.5/mod_msg.c:75:3:  [2] (buffer) char:
  Statically-sized arrays can be improperly restricted, leading to potential
  overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
  functions that limit length, or ensure that the size is larger than the
  maximum possible length.
