FINAL RESULTS:

data/ruby-hiredis-0.6.3/ext/hiredis_ext/connection.c:47:5:  [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.
