October 14, 2011

quassel vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

• Ubuntu 11.04
• Ubuntu 10.10
• Ubuntu 10.04 LTS

Summary:

An unprivileged user could read files in the data and logging directories,
including an automatically generated SSL certificate, used by the quasselcore
daemon.

Software Description:

• quassel: KDE/Qt-based IRC client

Details:

Felix Geyer discovered that the quassel-core post installation script created
data and logging directories which were readable by all users. The post
installation script also generated a certificate, in the data directory, which
was readable by all users.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 11.04:
quassel-core 0.7.2-0ubuntu2.3

Ubuntu 10.10:
quassel-core 0.7.1-0ubuntu1.2

Ubuntu 10.04 LTS:
quassel-core 0.6.1-0ubuntu1.3

In general, a standard system update will make all the necessary changes.
