FINAL RESULTS:

data/ltpanel-0.2/src/lpanel.c:795:2:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
	sprintf(matchme, "%s%%i", pattern);	/* eg: -n=%i */
data/ltpanel-0.2/src/lpanel.c:796:6:  [4] (buffer) sscanf:
  The scanf() family's %s operation, without a limit specification, permits
  buffer overflows (CWE-120, CWE-20). Specify a limit to %s, or use a
  different input function. If the scanf format is influenceable by an
  attacker, it's exploitable.
	if (sscanf(arg, matchme, &n) > 0) {
data/ltpanel-0.2/src/lpanel.c:792:5:  [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.
    char matchme[6];
data/ltpanel-0.2/src/lpanel.c:413:8:  [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).
	len = strlen(tk->name);
