Examining data/empire-hub-1.0.2.2/hub.c

FINAL RESULTS:

data/empire-hub-1.0.2.2/hub.c:209:2:  [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(line,com->buffer,len);	
data/empire-hub-1.0.2.2/hub.c:1166:27:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
	sock_in.sin_port = htons(atoi(port));
data/empire-hub-1.0.2.2/hub.c:1170:26:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
	listen_fd = open_listen(atoi(localport));
data/empire-hub-1.0.2.2/hub.c:136:2:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
	strncpy(str,line+start,end-start+1);
data/empire-hub-1.0.2.2/hub.c:360:2:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
	strncpy(args,line+first,last-first+1);
data/empire-hub-1.0.2.2/hub.c:381:2:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
	strncpy(command,line+start,end-start);
