[Typo3] Bug 0000416. Typo3 3.6.2 What am I supposed to do?

[mario]

Hi all

i just discovered that my version 3.6.2 is buggy. It is the well known
bug 416 (see at http://bugs.typo3.org/view.php?id=416) 
I understand this has been fixed in the new version (correct?)
But, is there something  I am supposed to do with the attached files at
the bug page above?
My main question is: is there a quick fix for my version? 

Thanks a lot
mario
