FINAL RESULTS:
data/arp-scan-1.9.7/error.c:92:4: [4] (format) vsnprintf:
If format strings can be influenced by an attacker, they can be exploited,
and note that sprintf variations do not always \0-terminate (CWE-134). Use
a constant for the format specification.
vsnprintf(buf, MAXLINE, fmt, ap);
data/arp-scan-1.9.7/link-dlpi.c:117:11: [4] (buffer) sscanf:
The scanf() family's %s operation, without a limit specification, permits
buffer overflows (CWE-120, CWE-20). Specify a limit to %s, or use a
different input function.
if (sscanf(p, "%s (PPA %d)\n", dev, &ppa) != 2)
