FINAL RESULTS:

data/asclock-2.0.12/config.c:89:4:  [5] (buffer) strncat:
  Easily used incorrectly (e.g., incorrectly computing the correct maximum
  size to add) [MS-banned] (CWE-120). Consider strcat_s, strlcat, snprintf,
  or automatically resizing strings. Risk is high; the length parameter
  appears to be a constant, instead of computing the number of characters
  left.
	  strncat(ret, input, MAX_PATH_LEN);      
data/asclock-2.0.12/asclock.c:249:12:  [4] (shell) system:
  This causes a new program to execute and is difficult to use safely
  (CWE-78). try using a library call that implements the same functionality
  if available.
	      ret=system(exec_str);
data/asclock-2.0.12/config.c:137:3:  [4] (buffer) strcpy:
