FINAL RESULTS:

data/libcrypt-blowfish-perl-2.14/blowfish.h:3:18:  [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.
typedef unsigned char bf_cblock[8];
data/libcrypt-blowfish-perl-2.14/_blowfish.c:429:8:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120). Risk is low because the source is a
  constant string.
       strncpy((char *)bfkey, "Bad initialization data",24);
data/libcrypt-blowfish-perl-2.14/_blowfish.c:444:3:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120). Risk is low because the source is a
  constant string.
		strncpy((char *)bfkey, "Error in crypt_block routine",29);
