FINAL RESULTS:

data/minizip-1.1/miniunz.c:142:3:  [4] (buffer) strcpy:
  Does not check for buffer overflows when copying to destination [MS-banned]
  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused).
  strcpy(buffer,newdir);
data/minizip-1.1/crypt.h:112:9:  [3] (random) srand:
  This function is not sufficiently random for security-related functions
  such as key and nonce creation (CWE-327). Use a more secure technique for
  acquiring random values.
        srand((unsigned)(time(NULL) ^ ZCR_SEED2));
data/minizip-1.1/crypt.h:100:14:  [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.
    unsigned char header[RAND_HEAD_LEN-2]; /* random header */
data/minizip-1.1/ioapi.c:97:16:  [2] (misc) fopen:

  force the opening of special file type (e.g., device files), move things
  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).
