FINAL RESULTS:

data/gvidm-0.8/vidmode.cc:88:4:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
			sprintf(label_str, "Screen %s%i", i<10?"_":"", i);
data/gvidm-0.8/gvid.cc:129:9:  [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(argc,argv,shopt,lopt,lidx) getopt(argc,argv,shopt)
data/gvidm-0.8/gvid.cc:129:48:  [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.
#define getopt_long(argc,argv,shopt,lopt,lidx) getopt(argc,argv,shopt)
data/gvidm-0.8/gvid.cc:148:18:  [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.
	while (-1 != (c=getopt_long(argc, argv, "hlqr", long_options, NULL))) {
data/gvidm-0.8/vidmode.cc:33:9:  [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).
	return atoi(oss.str().c_str());
data/gvidm-0.8/vidmode.cc:62:2:  [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 label_str[80];
