    <p>
    KSirc fails to check the size of an incoming PRIVMSG string sent from
    an IRC server during the connection process.
    </p>
  </description>
  <impact type="normal">
    <p>
    A malicious IRC server could send a long PRIVMSG string to the KSirc
    client causing an assertion failure and the dereferencing of a null
    pointer, resulting in a crash.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All KSirc users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=kde-base/ksirc-3.5.5-r1"</code>
