how do I install / update to my system?
Normally you should patch the file(s) in the source package.You can compile Dovecot from the official sources (apply the patch before), download/install Dovecot from Mercurial (hg.dovecot.org) or open a bugreport for the package maintainer so that the bug can be fixed for your distribution.
