Examining data/fake-1.1.11/send_arp/send_arp.c

FINAL RESULTS:

data/fake-1.1.11/send_arp/send_arp.c:95:1:  [4] (buffer) strcpy:
  Does not check for buffer overflows when copying to destination [MS-banned]
  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused).
strcpy(sa.sa_data,DEFAULT_DEVICE);
data/fake-1.1.11/send_arp/send_arp.c:90:1:  [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(pkt.sndr_ip_addr,&src_in_addr,IP_ADDR_LEN);
data/fake-1.1.11/send_arp/send_arp.c:91:1:  [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(pkt.rcpt_ip_addr,&targ_in_addr,IP_ADDR_LEN);
data/fake-1.1.11/send_arp/send_arp.c:115:17:  [2] (buffer) bcopy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
                bcopy(hostp->h_addr,in_addr,hostp->h_length);
