FINAL RESULTS:

data/faultstat-0.01.05/faultstat.c:127:64:  [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.
	void (*df_printf)(const char *str, ...) __attribute__((format(printf, 1, 2)));

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

  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
	__attribute__((format(printf, 1, 2)));
data/faultstat-0.01.05/faultstat.c:387:8:  [4] (format) vsnprintf:
  If format strings can be influenced by an attacker, they can be exploited,
  and note that sprintf variations do not always \0-terminate (CWE-134). Use
  a constant for the format specification.

data/faultstat-0.01.05/faultstat.c:1549:11:  [3] (buffer) getopt:

  (CWE-120, CWE-20). Check implementation on installation, or limit the size
  of all string inputs.

  functions that limit length, or ensure that the size is larger than the
  maximum possible length.

data/faultstat-0.01.05/faultstat.c:236:7:  [2] (misc) open:
  Check when opening files - can an attacker redirect it (via symlinks),
  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).
