https://launchpad.net/bugs/49601
==========================
==========================
=========
A security issue affects the following Ubuntu releases:
Ubuntu 6.06 LTS
This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 6.06 LTS:
dovecot-common 1.0.beta3-3ubuntu5.2
dovecot-imapd 1.0.beta3-3ubuntu5.2
In general, a standard system upgrade is sufficient to effect the
necessary changes.
Details follow:
USN-288-3 fixed a vulnerability in dovecot. Unfortunately the Ubuntu
6.06 update had a regression which caused authentication using a MySQL
database to not work any more. This update fixes this again.
We apologize for the inconvenience.
