23rd September, 2010
A security issue affects these releases of Ubuntu and its derivatives:

Jima discovered that quassel would respond to a single privmsg
containing multiple CTCP requests with multiple NOTICEs, possibly
resulting in a denial of service against the IRC connection.
The problem can be corrected by updating your system to the following package version:

- quassel-core 0.6.1-0ubuntu1.1
- quassel 0.6.1-0ubuntu1.1

- quassel 0.4.1-0ubuntu3.1
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system update you need to restart quassel or
quasselcore to make all the necessary changes.
