FINAL RESULTS:

data/printer-driver-indexbraille-1.2.3/filter/index-direct-braille.c:31:8:  [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 buf[8096];
data/printer-driver-indexbraille-1.2.3/filter/index-direct-braille.c:113:11:  [2] (misc) open:
  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).
		input = open(argv[6], O_RDONLY);
data/printer-driver-indexbraille-1.2.3/filter/index-direct-braille.c:144:19:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
		ssize_t bytes = read(input, buf, sizeof(buf));
