  <synopsis>

    of arbitrary code or Denial of Service.

  <background>
    <p>
    Gaim is a full featured instant messaging client which handles a
    variety of instant messaging protocols.
    </p>

  <description>
    <p>
    Stu Tomlinson discovered that Gaim is vulnerable to a remote stack
    based buffer overflow when receiving messages in certain protocols,
    like Jabber and SILC, with a very long URL (CAN-2005-1261). Siebe
    Tolsma discovered that Gaim is also vulnerable to a remote Denial of
    Service attack when receiving a specially crafted MSN message
    (CAN-2005-1262).
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker could cause a buffer overflow by sending an
    instant message with a very long URL, potentially leading to the
    execution of malicious code. By sending a SLP message with an empty
    body, a remote attacker could cause a Denial of Service or crash of the
    Gaim client.
    </p>
  </impact>
  <workaround>
    <p>
    There are no known workarounds at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Gaim users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-im/gaim-1.3.0"</code>
  </resolution>
