2.  Impact Information

Background

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

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).

Workaround

There is no known workaround at this time.

Resolution

All Quassel users should upgrade to the latest version:
