data/wf-recorder-0.2.1/src/main.cpp:619:16:  [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((c = getopt_long(argc, argv, "o:f:m:x:g:c:p:d:b:la::te::h", opts, &i)) != -1)
data/wf-recorder-0.2.1/src/frame-writer.cpp:196:5:  [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.

data/wf-recorder-0.2.1/src/frame-writer.cpp:562:5:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.

data/wf-recorder-0.2.1/src/main.cpp:131:14:  [2] (tmpfile) mkstemp:
  Potential for temporary file vulnerability in some circumstances. Some
  older Unix-like systems create temp files with permission to write by all
  by default, so be sure to set the umask to override this. Also, some older
  Unix systems might fail to use O_EXCL when opening the file, so make sure
  that O_EXCL is used by the library (CWE-377).
    int fd = mkstemp(name);
data/wf-recorder-0.2.1/src/main.cpp:652:34:  [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).
