Examining data/longrun-0.9/longrun.c

FINAL RESULTS:

data/longrun-0.9/longrun.c:128:2:  [4] (format) vfprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
	vfprintf(stderr, fmt, arg_ptr);
data/longrun-0.9/longrun.c:139:2:  [4] (format) vfprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
	vfprintf(stderr, fmt, arg_ptr);
data/longrun-0.9/longrun.c:541:14:  [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.
	while ((g = getopt(argc, argv, "c:f:m:hlpstv")) != EOF) {
data/longrun-0.9/longrun.c:150:7:  [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).
	nb = open(LR_NORTHBRIDGE, O_RDONLY);
data/longrun-0.9/longrun.c:169:7:  [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).

data/longrun-0.9/longrun.c:589:18:  [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).
