FINAL RESULTS:

data/libutempter-1.1.6/iface.c:63:2:  [4] (shell) execv:
  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.
	execv(path, argv);
data/libutempter-1.1.6/iface.c:82:10:  [4] (shell) execv:
  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.
		(void) execv(path, argv);
data/libutempter-1.1.6/utempter.c:51:40:  [4] (format) printf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
static void __attribute__ ((__format__(printf,1,2)))
data/libutempter-1.1.6/utempter.c:168:2:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
	strncpy(ut.ut_name, user, sizeof(ut.ut_name));
data/libutempter-1.1.6/utempter.c:169:2:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
	strncpy(ut.ut_line, term, sizeof(ut.ut_line));
data/libutempter-1.1.6/utempter.c:171:3:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
		strncpy(ut.ut_host, host, sizeof(ut.ut_host));
data/libutempter-1.1.6/utempter.c:175:12:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
	offset = (strlen(term) <= sizeof(ut.ut_id)) ? 0 :
data/libutempter-1.1.6/utempter.c:176:4:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
			strlen(term) - sizeof(ut.ut_id);
data/libutempter-1.1.6/utempter.c:178:2:  [1] (buffer) strncpy:
