FINAL RESULTS:

data/drawtiming-0.7.1/src/parser.cc:607:21:  [4] (format) fprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
#  define YYFPRINTF fprintf
data/drawtiming-0.7.1/src/main.cc:28:11:  [3] (buffer) getopt_long:
  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.
#  define getopt_long(C,V,S,O,I) getopt(C,V,S)

  of all string inputs.

data/drawtiming-0.7.1/src/main.cc:112:25:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).

  input had no minus sign (large numbers can roll over into negative number;

data/drawtiming-0.7.1/src/main.cc:186:14:  [2] (misc) fopen:
  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).
      yyin = fopen (argv[i], "rt");
data/drawtiming-0.7.1/src/parser.cc:904:7:  [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.

data/drawtiming-0.7.1/src/parser.cc:785:21:  [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).
#   define yystrlen strlen
data/drawtiming-0.7.1/src/scanner.cc:536:14:  [1] (buffer) getc:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
