    <p>
    KVIrc is a free portable IRC client based on Qt.
    </p>

  <description>
    <p>
    Stefan Cornelius from Secunia Research discovered that the
    "parseIrcUrl()" function in file src/kvirc/kernel/kvi_ircurl.cpp does
    not properly sanitise parts of the URI when building the command for
    KVIrc's internal script system.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a specially crafted
    irc:// URI, possibly leading to the remote execution of arbitrary code
    with the privileges of the user running KVIrc. Successful exploitation
    requires that KVIrc is registered as the default handler for irc:// or
    similar URIs.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All KVIrc users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-irc/kvirc-3.2.6_pre20070714&quot;</code>
  </resolution>
