This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchown( ) instead.
if (chown(dest_path, sbuf.st_uid, sbuf.st_gid) != 0)
data/optipng-0.7.7/src/optipng/ioutil.c:525:9: [5] (race) chmod:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchmod( ) instead.

(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.
