To fix it (as root) run...
chmod 4750 /u01/app/oracle/product/12.1.0.2/bin/extjob
chown root:oinstall /u01/app/oracle/product/12.1.0.2/bin/extjob

Additional Information
You can also use the relink command to relink a subset of the Oracle installation. Options include:
relink all
The "relink all" command will not actually relink every single executable Oracle provides (you can discern which executables were relinked by checking their timestamp with 'ls -l' in the $ORACLE_HOME/bin directory). However, 'relink all' will recreate the shared libraries that most executables rely on and thereby resolve most issues that require a proper relink.relink oracle
