Yes those 4 files will patch your system.

About the exploit:

coppermine OR error.php is used to send over a script.
The script CAN'T run on its own so it needs a file that has a bug.
install.php has such bug in the language selector.

If you properly deleted the install.php per the instructions said, then your system is not vulnerable.
Since both the readme and the installer say it, this exploit is actualy "low-risk". But since nobody does what they read or skip to read i've put it up as update notification.

The XSS exploit i discovered in linking.php is of a much more severe security issue. Therefore the update notification is fully in its right.

OK, I did follow the install instructions and removed install.php. However I'm not clear if the linking.php issue mentioned above is seperate? My update notification just talks about removing the install, with no mention of an XSS exploit in linking.php.

So can someone clarify that if I don't have install.php I'm safe from everything discussed here including the linking.php XSS exploit?
