FINAL RESULTS:

data/sucrack-1.2.3/src/pty.c:51:5:  [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(mdev, PTY_DEVICE_NAME);
data/sucrack-1.2.3/src/pty.c:54:5:  [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(sdev, TTY_DEVICE_NAME);
data/sucrack-1.2.3/src/su.c:131:5:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
    sprintf(send_buf, "%s\n", pass);
data/sucrack-1.2.3/src/su.c:190:9:  [4] (race) access:
  This usually indicates a security flaw. If an attacker can change anything
  along the path between the call to access() and the file's actual use
  (e.g., by moving files), the attacker can exploit the race condition
  (CWE-362/CWE-367!). Set up the correct permissions (e.g., using setuid())
  and try to open the file directly.

  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.

data/sucrack-1.2.3/src/util.h:47:34:  [4] (format) fprintf:

data/sucrack-1.2.3/src/su.c:172:12:  [3] (buffer) getenv:
  Environment variables are untrustable input if they can be set by an
  attacker. They can have any content and length, and the same variable can
  be set more than once (CWE-807, CWE-20). Check environment variables
  carefully before using them.

data/sucrack-1.2.3/src/sucrack.c:129:16:  [3] (buffer) getopt:
  Some older implementations do not protect against internal buffer overflows
  (CWE-120, CWE-20). Check implementation on installation, or limit the size
  of all string inputs.
