FINAL RESULTS:
data/rdup-1.1.15/dir.c:25:6: [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(p, s->st_mode | S_IWUSR) == -1) {
data/rdup-1.1.15/dir.c:38:6: [5] (race) chmod:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchmod( ) instead.

data/rdup-1.1.15/fs-up.c:74:2: [5] (race) chmod:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchmod( ) instead.
chmod(e->f_name, e->f_mode);
data/rdup-1.1.15/link.c:35:11: [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.

data/rdup-1.1.15/rm.c:115:4: [5] (race) chmod:

data/rdup-1.1.15/rm.c:120:5: [5] (race) chmod:

data/rdup-1.1.15/child.c:144:8: [4] (shell) execvp:

if available.

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())

are excessively vulnerable to dictionary attacks given today's faster

with a larger, non-repeating salt.
