FINAL RESULTS:
data/scheme9-2018.12.05/ext/sys-unix/unix.c:163:6: [5] (race) chmod:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchmod( ) instead.
r = chmod(string(parg(1)), integer_value("sys:chmod", parg(2)));
data/scheme9-2018.12.05/ext/sys-unix/unix.c:171:6: [5] (race) chown:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchown( ) instead.
r = chown(string(parg(1)),
data/scheme9-2018.12.05/ext/sys-unix/unix.c:601:6: [5] (race) readlink:
This accepts filename arguments; if an attacker can move those files or
change the link content, a race condition results. Also, it does not
terminate with ASCII NUL. (CWE-362, CWE-20). Reconsider approach.
k = readlink(string(parg(1)), buf, MAXPATHLEN);
data/scheme9-2018.12.05/attic/sys-plan9/plan9.c:556:3: [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).

(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.
