Examining data/oggfwd-0.2/oggfwd.c

FINAL RESULTS:

data/oggfwd-0.2/oggfwd.c:116:15:  [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 ((ch = getopt(argc, argv, "d:g:hn:pu:")) != -1) {
data/oggfwd-0.2/oggfwd.c:106:11:  [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.
	unsigned char	buff[BUFFERSIZE];
data/oggfwd-0.2/oggfwd.c:87:8:  [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).
	siz = strlen(opt) + 1;
