FINAL RESULTS:

data/devio-1.2/src/devio.c:1516:6:  [4] (format) printf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.

data/devio-1.2/src/devio.c:130:2:  [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(to, from, cb);
data/devio-1.2/src/devio.c:250:11:  [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).
	int fd = open(pname, (fwrite && !fverify) ? O_RDWR : O_RDONLY);
data/devio-1.2/src/devio.c:341:4:  [2] (buffer) memcpy:

  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.
