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

2.  Impact Information


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


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).


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.

3.  Resolution Information


There is no known workaround at this time.


All Quassel users should upgrade to the latest version:

Code Listing 3.1: Resolution

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