Examining data/haskell-crypto-random-0.0.9/cbits/rdrand.c

FINAL RESULTS:

data/haskell-crypto-random-0.0.9/cbits/rdrand.c:81:3:  [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(buffer, (uint8_t *) &tmp, to_alignment);
