Synopsis
========

Two vulnerabilities in Quassel may result in Denial of Service or SQL
injection.

Background
==========

Quassel is a Qt4/KDE4 IRC client suppporting a remote daemon for 24/7
connectivity.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-irc/quassel              < 0.9.1                    >= 0.9.1

Description
===========

Two vulnerabilities have been found in Quassel:

* Quassel does not properly handle multiple CTCP requests
  (CVE-2010-3443).
* Quassel, when used with certain versions of Qt and PostgreSQL, does
  not sanitize user input (CVE-2013-4422).

Impact
======

A remote attacker could send multiple CTCP requests in single private
message, possibly resulting in a Denial of Service condition.
Futhermore, a remote attacker may be able to execute arbitrary SQL
statements.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Quassel users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=net-irc/quassel-0.9.1"
