Examining data/pathological-1.1.3/write-highscores.c

FINAL RESULTS:

data/pathological-1.1.3/write-highscores.c:31:10:  [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 buffer[BUFFER_SIZE];
data/pathological-1.1.3/write-highscores.c:44:12:  [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).
	if( (fd = open( HIGHSCORES, O_WRONLY | O_TRUNC )) == -1) die();
data/pathological-1.1.3/write-highscores.c:46:17:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
	while( (size = read( 0, buffer, BUFFER_SIZE)) > 0) {
