    <p>
    Asterisk is an open source telephony engine and tool kit.

  <description>
    <p>
    Asterisk upstream developers reported multiple vulnerabilities:
    </p>
    <ul>
    <li>The Call Detail Record Postgres logging engine (cdr_pgsql)
    does not correctly escape the ANI and DNIS arguments before using them
    in SQL statements (CVE-2007-6170).</li>
    <li>When using database-based
    registrations ("realtime") and host-based authentication, Asterisk does
    not check the IP address when the username is correct and there is no
    password provided (CVE-2007-6430).</li>
    <li>The SIP channel driver does
    not correctly determine if authentication is required
    (CVE-2008-1332).</li>
    </ul>
  </description>
  <impact type="normal">
    <p>
    Remote authenticated attackers could send specially crafted data to
    Asterisk to execute arbitrary SQL commands and compromise the
    administrative database. Remote unauthenticated attackers could bypass
    authentication using a valid username to hijack other user's sessions,
    and establish sessions on the SIP channel without authentication.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Asterisk users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-misc/asterisk-1.2.27"</code>
  </resolution>
