FINAL RESULTS:
data/pdns-recursor-4.4.1/pdns_recursor.cc:2054:8: [5] (race) chown:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchown( ) instead.
if(chown(sockname.c_str(), sockowner, sockgroup) < 0) {
data/pdns-recursor-4.4.1/pdns_recursor.cc:2062:8: [5] (race) chmod:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchmod( ) instead.
if(chmod(sockname.c_str(), sockmode) < 0) {
data/pdns-recursor-4.4.1/rec_channel.cc:122:8: [5] (race) chmod:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchmod( ) instead.

data/pdns-recursor-4.4.1/dnsname.cc:449:18: [4] (format) snprintf:
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.
auto got = snprintf(buf, sizeof(buf), "%03" PRIu8, p);
data/pdns-recursor-4.4.1/ext/json11/json11.hpp:65:17: [4] (format) snprintf:
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.
#ifndef snprintf
data/pdns-recursor-4.4.1/ext/json11/json11.hpp:66:21: [4] (format) snprintf:
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.
#define snprintf _snprintf_s
data/pdns-recursor-4.4.1/pdns_recursor.cc:4193:12: [4] (race) access:
This usually indicates a security flaw. If an attacker can change anything
along the path between the call to access() and the file's actual use
(e.g., by moving files), the attacker can exploit the race condition
(CWE-362/CWE-367!). Set up the correct permissions (e.g., using setuid())
and try to open the file directly.

data/pdns-recursor-4.4.1/pdns_recursor.cc:4625:11: [3] (buffer) getenv:
Environment variables are untrustable input if they can be set by an
attacker. They can have any content and length, and the same variable can
be set more than once (CWE-807, CWE-20). Check environment variables
carefully before using them.
ns = getenv("NOTIFY_SOCKET");
data/pdns-recursor-4.4.1/pdns_recursor.cc:4631:9: [3] (misc) chroot:
chroot can be very helpful, but is hard to use correctly (CWE-250, CWE-22).
Make sure the program immediately chdir("/"), closes file descriptors, and
drops root privileges, and that all necessary files (and no more!) are in
the new root.
