Examining data/rig-1.11/rig.cc

FINAL RESULTS:

data/rig-1.11/rig.cc:55:2:  [3] (random) srand:
  This function is not sufficiently random for security-related functions
  such as key and nonce creation (CWE-327). Use a more secure technique for
  acquiring random values.
	srand(time(NULL) ^ (((unsigned int) getpid()) << 15));
data/rig-1.11/rig.cc:66:2:  [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+written, &tmp, bytestocopy);
data/rig-1.11/rig.cc:40:13:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
    urandev.read((char*)&rval, sizeof(rval));
data/rig-1.11/rig.cc:48:14:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
      randev.read(&rval, sizeof(rval));

Not every hit is necessarily a security vulnerability.
There may be other security vulnerabilities; review your code!
