data/vanessa-logger-0.0.10/libvanessa_logger/vanessa_logger.c:387:7:  [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).
		    fopen(vl->data.d_filename->filename, "a");

		    fopen(vl->data.d_filename->filename, "a");
data/vanessa-logger-0.0.10/libvanessa_logger/vanessa_logger.c:577:3:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
		memcpy(vl->buffer + offset, prefix, len - 2);
data/vanessa-logger-0.0.10/libvanessa_logger/vanessa_logger.c:578:3:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).

  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
	memcpy(vl->buffer + offset, fmt, len);
data/vanessa-logger-0.0.10/libvanessa_logger/vanessa_logger.c:1078:8:  [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.
static char vanessa_logger_strherror_str[34];
data/vanessa-logger-0.0.10/libvanessa_logger/vanessa_logger.c:1126:2:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
	memcpy(buf, str, len);
data/vanessa-logger-0.0.10/libvanessa_logger/vanessa_logger.c:1292:3:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
		sprintf(out_pos, "%02x", *in_pos);
data/vanessa-logger-0.0.10/libvanessa_logger/vanessa_logger.c:573:9:  [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).
		len = strlen(prefix) + 2;
data/vanessa-logger-0.0.10/libvanessa_logger/vanessa_logger.c:582:8:  [1] (buffer) strlen:
